Friction Heat in Coupled Field Transient

    • Metehan Emirzeoğlu

      Dear Ansys Users;

      Since my research location is related to the frictional behavior of 3D solid models, I wanted to start my tests with simple models as seen in the photo. I think I can perform my tests in Couple Field Transient analysis since I can control the mechanical and thermodynamic properties of the models in the same way. When the connection between the two parts is no separation, the problem is being solved; When the connection in question is defined as friction, the problem gives the error in the photo. I just entered the coefficient of friction to define the friction link and left everything else to program control. Since the connection type is frictional, I assigned a convection coefficient to the material against the heat that will occur.

      When I watched other videos on the internet, I noticed that friction problems were solved in Couple Field Transient with 2D analysis or in Transient Structural using APDL. However, these solutions will not work on advanced models. I would be glad if you could help me to solve this problem.

      There is an example similar to what you are trying to model above, in our help manual and under the workbench techn. show cases:

      All the best
