I am having some trouble getting my fully coupled thermal stress model to converge with higher density meshes. I have lowered the increment size in the past to get it converge but now I get this error related to heat flux.
There is zero HEAT FLUX everywhere in the model based on the default criterion. please check the value of the average HEAT FLUX during the current iteration to verify that the HEAT FLUX is small enough to be treated as zero. if not, please use the solution controls to reset the criterion for zero HEAT FLUX.
I guess my problem is that I don’t understand exactly what the increment size is and I was wondering if someone could give me some direction.
Thanks
