Hi,

I'm running a chtMultiRegionSimpleFoam + thermalBaffles3D case.
I can't understand what is the source of this problem and where to look for a solution.
This is the error message:

Solving for fluid region domain0
DILUPBiCG:  Solving for Ux, Initial residual = 1, Final residual = 0.00849631, No Iterations 1
DILUPBiCG:  Solving for Uy, Initial residual = 1, Final residual = 0.01094487, No Iterations 1
DILUPBiCG:  Solving for Uz, Initial residual = 1, Final residual = 0.0118836, No Iterations 1
