Radioss Viscoelastic dissipation

Dear community,

Question context: I am trying to use Radioss to simulate the ultrasonic welding process. During ultrasonic welding, vibration energy is dissipated viscoelastically, leading to local heating. I want to use the energy dissipated as a heat source for heating simulation, to compute viscoelastic heating.

Question: How can I obtain the viscoelastic dissipation energy at nodal locations throughout the dynamic vibration simulation?

Thank you!
