Hello, I am trying to simulate Joule heating model in Comsol multiphysycs heat transfer module. I want to use joule heating till the 19 sec. After 19 I want to stop JH and continue convective cooling till 240 sec. For the moment I just did joule heating to 19 sec. Tried to use 2 step solver but it doesn't obtain. If anyone can help me I will appreciate it. Thank you !
