Hello,
I am running a 3D stationary model that includes flow+HT+surface-to-surface radiation nodes. There are two domains (solid inside a fluid domain(gas)). There is an inlet/oulet in the domain while a heater is generating heat inside the solid domain. Heat needs to be ejected via radiation and convection from the system.
I can run flow node separately. I can run HT in solid and fluid+radiation nodes separately.
When I want to run all at the same time, I get "- Detail: NaN or Inf found when solving linear system using PARDISO."
This should relate to coupling between flow and heat. I am not sure how to tackle this issue. I have used ramping/auxiliary sweep but with no luck.
I appreciate any hints.
