Thermostructural Analysis & Friction

Is possible make a thermostructural simulation in simscale whit friction, stresses and temperature? this its for a transient simulation in disc brake

example using ansys
Example using Abaqus

Hi @cdiaz, there are two missing features which prevent this at the moment:

  • taking into account heat generated by friction
  • moving thermal contact zones

You can do a thermomechanical analysis which has friction enabled, but it is only taken into account for the mechanical part of the analyses. SimScale is currently using a chained approach for the thermomechanical analysis, this means at first the thermal computation is carried out and then its results are used as input for the structural analyses. This is why changes in the structural part do no get represented in the thermal analysis, and thus the two short-comings mentioned above.
