Import An Input Stress-Strain Initial State From Abaqus To Comsol

Please login with a confirmed email address before reporting spam

Dear all I was wondering if it would be possible to import the deformed mesh/geometry and an input file with the stress-strain data after a solid mechanics analysis made in ABAQUS to define an initial state in COMSOL in order to use that geometry and those stress-strain results in other COMSOL's modules. Can anybody help me? Any help is appreciated.

Check if ABAQUS can export the deformed geometry in one of these formats. https://www.comsol.com/products/specifications/cad/

Then you can import that into COMSOL.

You may be able to define an interpolation function in COMSOL that uses data exported from ABAQUS as an initial stress/strain. See this.

Granted since COMSOL has functionality to do this entirely within COMSOL, you might as well make life easier by solving the solid mechanics problem in COMSOL.

We all have opinions. But the COMSOL support team has the truth. I don't know if my opinion is still the truth. Check with that team before you try this at home!
