I assume you are doing a static analysis. Thermal stress should increase with increase temperature. I dont know how you are applying temperature on you model, but you should get maximum stress at the clamped area. Having said that, make sure you have a decently good mesh, and you take reading...

Why dont you definie Anisotropic material for that specific volume? You can define properties in a 6 x 6 matrix in ANSYS. I dont how many elements you plan to use, but defining a matrix for each element is generally unrealistic. Haris

1- This could be done in two steps. a- Use VSYMM to generate a symmetric volume. b- Use VGENN to move that volume to specific distance you want. When using VGENN, make sure you select 'move original volume' option, and NOT 'generate additional volumes'. 2- To select an area using...

Did you try importing it in Parasolid format? You might wanna check if the lines of two volumes are not overlapping each other.

Thanks for the reply. No, the actual geometry is going to be pretty complicated. Also, I tried making a separate volume within cylinder. It increases the number of elements significantly. With actual model, it will take forever to finish the simulation.

Hello All I've recently started using Mechanica (wildfire 4.0) for prelimanary analyses, instead of ANSYS. Just to verify results, I am running a modal analysis on a cylinder to get displacement distribution along the length of the cylinder. I get results, and they match my calculations. Now I...
