AutoFEM Analysis Checking 3D model geometry | |
•Mode Check 3D model representation activates the regime of testing the geometry of the 3D model using its current PLC presentation. When possible inaccuracies in the presentation of the 3D model are found, they are shown in the Preprocessor window; also the "Geometry" window shows the number of suspicious objects being found. If these errors do not vanish at the change of mesh construction parameters, the user must analyse the initial AutoCAD 3D model in the fields, marked during the diagnosis process, and correct the 3D model to eliminate the errors.
Possible problem areas are shown in the model
•Mode Find suspicious geometry. This mode allows to find very small entities of the 3D model such as extremely small steps, fillets or chamfers, which can prevent the successful creation of the tetrahedral finite element mesh (the mesh generator cannot divide them into tetrahedrons). If the mesh is not created, you should modify these elements of geometry to eliminate errors. Aspect ratio defines the threshold value when the object may be considered as an erroneous object.
