Hello,
now i'm doing FYP, i need to analyze a welding branch in pipe using ansys workbench 13.
First I analyze using steady state thermal then i need to couple the model to statical structural (pressure).
i have a problem to make couple model. i can link engineering data to engineering data, geometry to geometry, solution to setup, but why i cant link model to model?

The other problem is i cant define new material in ansys 13. Actually i import the geometry from autodesk inventor. Thanks.
