I am modifing the heat transfer model and would like to test it in a fixed particle arrangement. I can simulate this as usual, but therefore the timestep has to be quite small. I wonder if I could deactivate the particle motion, so that just the heat transfer is solved? Then I could choose a way bigger timestep.
I tried to set pair style to none, but this is not possible since the heat transfer fix requires a pair style. And if I remove the integration fix, the temperature is also not calculated.
I came to the conclusion, that it is not possible and that I would need to modify the soruce code and recompile. Would you agree or is there any other option?
Thank you for your help or just your thoughts on it.
