problem with large strain simulation
problem with large strain simulation
(OP)
Dear all,
3D model --> solid186
nonlinearities : BISO and large strain
I have convergence trouble with a large strain simulation. During the simulation, Ansys tell me that "element xxx is turning inside out". I tray to change the mesh density,
reduce the load step, change the element type... but no good results. It is possible to remesh my volume during the simulation??? Somebody know someting to do?
tanks in advance

RE: problem with large strain simulation
If you are applying an ideal elastic-plastic curve then try making the plastic part of the slope have a slight upward slope rather than it being horizontal, that helps convergence.
