Dear all,
I run steady state simulation with CHT. Convergence of fluid domains is reached quite fast (200 iterations). But then I need to wait another 500 iterations for convergence of solid domains. How to reach them faster? Does time scale factor for solids help? Or is there any other way? if so, does it affect RMS? Thank you in advance. Best regards |

It is common practice to use a solid timescale 1000 times (or more) larger than the fluid timescale for CHT problems.

Thank you Opaque for quick answer. Do you have experience if it changes RMS velues?

RMS values should not be a function of the physical timescale.
