  1. Hi everyone, I am trying to run a weakly-coupled solution (thermal and structural) with a custom MATUSR subroutine. If I define the properties using MAT1 and MAT4, it works perfectly fine (see the attached model brick_coupled_builtin.fem). If I define the properties using MATUSR and MAT4, I receive the following error: *** ERROR # 70 *** Thermal loads exist, and all material thermal expansion coefficients are zero. I did not see anywhere in the documentation whether MATUSR did or did not support extra material cards. Would you have any idea if that's possible? Thanks, Cédric brick_coupled_builtin.fem brick_coupled_matusr.fem matusr.F
  2. Hello everyone Can someone give me an advice on how to indicate that a certain surface have a temperature of 20°C and another surface of 80°C? And also indicate the pressure of those surfaces? In order to get thermal and mechanical results of it? I thank you in advance for your help!
  3. Hello Guys! I'm trying to perform an Thermal/Structural Analysis in Optistruct. But, I didn't found on tutorials, how can I input some structural loads, like forces, pressures and moments, working together with thermal loads, like heat flux and convection. I wish to learn how can i do this in a Steady-State and Transient Analysis. Would you help me? The model is a brake disc with a brake torque. Thanks in advance!
