I am now wondering which one to use.

My problem is conductive heat transfer in biological materials considering the thermomechanical interactions. I have installed ABAQUS, but after use, I find its precessing is not very good and I am told that ANSYS is better. Can anybody have experience give me some advice?

Thank you

Check the survey result..

Then you can get some idea for the preprocessor

I would recommend the following:

Pre/Postprocessing : PATRAN Solver: ABAQUS

Advantage: excellent Preproccesor for meshing and Geometrie Cleanup (much more easy to handle than Ansys) and the leading nonlinear FEM solver which is absolut reliable

hope this helps

I have some experience with ansys in heat transfer/structural mechanics problems. It is reliable and once you get used, its pre-processor is powerful (however if your problem is the mesh, try an independent mesher, eg patran, hypermesh, etc). You can do semi-coupled analyses between heat transfer/structural models.
