Mesh modification for more CPUs
 

Hello everyone.
I am simulating the occurrence of natural convection due to temperature gradient in a containment. The main goal is to discover the impact of natural convection on a stratified layer.
My current mesh consists of two connected domains - helium domain and air + steam domain. The upper - helium domain is smaller and has around 17000 nodes, the lower domain has about 190000 nodes.
So far I have been able to use 4 CPUs because of the Ovlp factor that should have the value no greater than 10%.
Is there any way I could modify my mesh and use more CPUs for my calculations?

Thank you in advance to anyone that might be able help me.

Which solver are you using?

I am using CFX
