Hello !
For my internship, I am doing a benchmark on thermal and thermomechanical analysis, particularly on mapping of thermal results. For this purpose, I am asked to establish a list of ways to add rotation dof to solids with ABAQUS, MSC NASTRAN and SAMCEF that could be compatible with thermomechanical cases (mainly the addition of thermal expansion). As of now, I have tested/selected the ones listed below :
-adding a perpendicular shell through SAMCEF sticking/MSC NASTRAN glue contact/ ABAQUS TIE, beam links or coincident nodes inside the volume,
-APS macro with SAMCEF (not tested but suggested by my tutors).
NB: the use of shells is standard procedure in the company.
I am considering :
-MSC NASTRAN RBE3,
—MSC NASTRAN GAP/CGAP
-adding a beam/rigid element linked to the solid the same way as the shells,
— ABAQUS shell to solid coupling,
— ABAQUS Rigid body constraint,
— ABAQUS General contact,
— ABAQUS Coupling constraint.
Does anyone have any remarks or other ideas regarding this topic?
Thank you in advance for your help !
