Are any techniques to converge granular temperature residual?

MFiX
#1

Dear experts,

I am trying MFiX simulation, and confronts convergence problems.
I understand that some fields have specific techniques for convergence (e.g. for gas/solid pressure, Fluid/Solids normalization should be set to be 0).

Sometimes, I am trouble in convergence of granular temperature (G1, G2 marks) .
Are any techniques to converge granular temperature residual?

Kind regards

You can try to adjust the Initial and Boundary condition values. For example if it is set to 1E-8, try 1E-6 m^2/s^2.

Thank you for your kind reply, I will try it.
