AutoFEM and other CAE systems comparison
( AutoFEM vs Ansys & SolidWorks Simulation )

We are often asked, "Does AutoFEM provide an acceptable precision of calculations? Is there any comparison AutoFEM and other famous finite element software systems?"
Below you can find a comparison of our tutorial examples, solved, besides AutoFEM, in two other well known finite element systems: ANSYS Workbench and SolidWorks Simulation (CosmosWorks).

Linear Static Strength Analysis

The result "Displacements" in AutoFEM Analysis:

The result "Displacements" in SolidWorks Simulation:

The result "Displacements" in Ansys Workbench:

Comparison:

Conclusion:
We can see, the maximal displacements are very close in spite of the difference between finite element meshes.

The result "Stresses von Mises" in AutoFEM Analysis:

The result "Stresses von Mises" in SolidWorks Simulation:

The result "Stresses von Mises" in Ansys Workbench:

Comparison:

Conclusion:
We can see fairly large disturbance in stress estimations between all FEA systems because of the finite element mesh coarseness.
