Hello,
We are trying to perform an FSI simulation using Code_Aster(+Mfront) + OpenFOAM.
In each iteration, we read a load file provided by OpenFOAM and apply it to the mesh in Code_Aster.
We are not entirely sure how Code_Aster works. Our intention is to apply the loads to the deformed mesh, not to the initial reference mesh. For this reason, in the DYNA_NON_LINE command we use the option:
EXCIT = _F(TYPE_CHARGE = "SUIV", ...).
Is this correct? I mean, does this command apply the loads on the deformed mesh or on the reference mesh?
Somebody has any light?
Regards,
Gerard
