New Features of AutoFEM Analysis 3.0

Supporting AutoCAD 2018

AutoFEM 3.0 is compatible with AutoCAD 2018. Starting from version 3.0 AutoFEM Analysis is supplied only with capacity of x64, i.e. now it is necessary to use AutoCAD x64 to operate the system. Therefore, support of AutoCAD 2007 -2009 has been terminated as they were supplied mainly in 32-bit version. So, the AutoFEM Analysis 3.0 supports operation with AutoCAD x64 versions 2010, 2012-2018.

AutoFEM 3.0 supports AutoCAD 2018

Supporting ShipConstructor 2018

AutoFEM 3.0 supports integration with ShipConstructor 2015R1-2018R2. The opportunity to choose material library AutoFEM has become available in the integration dialogue, the system will obtain physical properties of materials from this library.

Opportunity to choose material library for work with ShipConstructor

New AutoFEM Launcher

The system has obtained a new tool for the application launch and work with the accompanying materials. AutoFEM 3.0 Launcher enables the launch of the system from a common interface, implementation of necessary language settings and license settings, obtaining access to files and accompanying materials such as help, lessons and verification patterns.

New AutoFEM Launcher

New computational capabilities

Computational capabilities of the system have been significantly expanded in version 3 AutoFEM Analysis. In particular, a new type of study has been added – Dynamic analysis. Dynamic analysis provides for the ability to model the behaviour of the system under the effects of time-varying environments (forces, displacements) and significantly extends the range of the system application.

New type of study - "Dynamic analysis"

Three options for solving dynamic studies have been implemented which differ in the method of creation and solution of studies. Dynamic analysis permits one to model the behaviour of a structure (including movables) under the effect of time-varying forces and moving bases (fixations). Solution of the dynamic studies are made successively at a specified time slot with a determined time step, i.e. there are results from the system, a “snapshot” at every time step. Thus, the volume of the obtained results can be very large. Three options for the studies of the dynamic analysis are available in AutoFEM Analysis.

Dynamics - Direct Integration

A total system of algebraic equations which are comparable with a similar statistical strength study in the sense of solution complexity, is solved in this type of dynamic study at each time step. The advantage of this method is found in its accuracy and the ability to use it in nonlinear problems. However, usage of the method for long time processes can be difficult because it’s time consumption can be unreasonably high.

Dialogue of dynamic analysis solver settings

Dynamics - Mode Superposition (Linear dynamics)

This type of study requires the availability of a calculated problem of frequency analysis. The dynamic study solution is presented in a mode-superposition method as a combination (sum) of previously calculated forms of system oscillations. Such a type of study requires preliminary solution of a frequency analysis problem in order to find Eigen forms (modes), of the system under study that can be unprofitable enough from the perspective of computation. However, if Eigen frequencies and modes are known, finding of a dynamic study solution will be very quick and efficient from the perspective of the required computational resources. That is why this method can be recommended for modeling relatively long processes with a great number of time steps.

Dynamics - Frequency & Mode Superposition

Mode-superposition method integrated with the solution of a frequency problem. A study can be created with no frequency problems in a document because such problems will be solved automatically before the launch of solution of a dynamic study.

Lifting and transporting operation of a vessel unit

As a result of this solution of the dynamic studies, we obtain a complete picture of the system’s behaviour – displacement, speed and stress in the system at any one time at the specified time slot.

Consideration of temperature dependences of material properties in mechanic and thermal studies

The ability to consider the impact of temperatures on construction material properties is added to mechanical and thermal studies. This permits one to evaluate more precisely strength and behaviour of the structure operated in an irregular temperature field.

Mode of consideration of dependences of material properties on temperature
during calculation is activated on the Thermal Effects tab.

Improvements in the thermal analysis module

Radiant heat exchange with re-reflections

Algorithms of calculation of radiant heat exchange have been improved, particularly, the ability to consider reciprocal re-reflections between bodies during heat exchange has been added.

Change of run of the command "Solve"

The general order of a calculation launch has been slightly changed. After setting of main options of a calculation, an additional dialogue appears in which the user is offered the opportunity to mark the results that should be saved. The system also displays an approximate volume of saved results (in MB) and available free space on the disk at that moment. This dialogue is especially useful in dynamic studies to which a large volume of generated data is specific.

First step - Static solver settings

Second step - dialogue of setting of the results to be saved

Now it has become possible for the user to assign a graph for any material parameter which displays dependence of such parameter on temperature. Accordingly, the system takes into consideration this dependence during calculation.

Temperature dependence curve can be created for every material parameter

Materials export-import

The ability to export materials to an external file in table format *.csv has been added as well as being able to import data from the same format. This facilitates significantly the addition of new data, concerning materials, to the library. The user can prepare a table containing materials data in an independent table editor (MS Excel, LibreOffice Calc, etc.) and then upload them to AutoFEM library.

1) Graph determined by values of the function in the assigned points ("Point-to-point graph");

2) Graph assigned by a continuous function ("Graph by formula").

Point-to-point graph of temperature dependence of the elastic modulus

Graph of temporal variation of force assigned by the function

Graphs can be exported, imported, saved as pictures, used in reports, etc.

New options of Mesh Generator

The system has found 14 solids without mesh - marked light green colour

Moving to another document

In several diagnostics modes (such as "Non contacting bodies" and "Solids without FE mesh") the user is able to transfer 3D model into another .DWG document. The new document will comprise the whole original 3D model, but each object listed on the geometry list will be placed on its own layer. Consequently, the user can then control the visibility of parts and analyse their geometry for errors.

The button "Move to another document" is active for certain diagnostics modes.
Non contacting parts are marked with light green colour.

The system creates layers for each object on the list

User is able to hide some parts to reveal failed parts and then analyse them

Only one Gravity can be determined in the study.

Gravity assignment is taken out as a separate command

Remote loads

Three new commands for the assignment of so called "Remote loads" have been added.

Remote loads

Remote force, moment

The command permits one to assign force action on a structure from any external object for which it is unreasonable (or impossible) for whatever reason to be included directly in the study. A classic example is the assessment of the resistance of a ship’s mast foundation to the wind load. In which case, an integral (aggregate) value of wind load and centre of application thereof is assigned.

Remote force/moment assignment command

Remote mass

The command permits transmission of mass-and-inertia effects of a structural member to the system without creating finite-element mesh and a model for such elements. For example, to transmit mass-and-inertia effects of an electric motor to a load-carrying structure. It is evident that if a problem is set to assess strength or dynamics of a load-carrying structure (bracket support), it is not reasonable nor always possible to construct a full-featured finite-element model of such a complex device as an electric motor. In this case, for the purpose of calculation it is enough to determine the location of a centre of mass and the relevant mass-and-inertia parameters of the electric motor which will impact on the load-carrying structure.

Remote mass assignment command

Remote displacement

Remote displacement permits one to transmit the effects of a known displacement of any remote structural member to the system, this member being connected to the structure by rigid connection.

Remote displacement assignment command

New command "Measure the model"

In the course of the analysis of structures, the necessity often arises to assess quickly mass-dimensional parameters of the modelled system. New command "Measure the model" permits one to take basic measurements of the structures. The command has three modes and permits one to take the following types of measurements:

• Geometric measurements - volumes and weight of bodies, surface area, length of ribs.

• Distance between two points of the model

• Distance from a point to geometry (ribs, facets)

Surface area measurement

Distance from a point to geometry (facet)

Improvements of the command Hydrostatic Pressure

Visual display of the assigned liquid level (semi-transparent circle in the middle of the coordinate system determining the liquid level) has been added to the command Hydrostatic pressure. Furthermore, the arrows showing direction of the pressure application have now different sizes depending on the depth which facilitates visual check of accuracy of the load application.

Better visualization of usage of the command "Hydrostatic pressure"

Improvements in the command Coordinate System

The ability to display names and numeric values of the coordinates of the center in the Pre-Post-processor window has been added to the user coordinate systems.

Name and coordinates of the user coordinate system can be displayed in the Preprocessor window

Improvements in the commands Sensor and Group of Sensors

Switch between Postprocessor windows

A group of special commands in the context menu on the active study and on the Results folder allows you to easily switch between the open result windows and automatically close them.

Commands for controlling the visibility of Postprocessor windows

Closing all AutoFEM's windows
