problem with chtMltiRegionFoam

Ahmed Khattab · December 17, 2012, 14:04

Hi Foamers,

i experienced a problem with chtMultiRegionFoam solver. i want to simulate flow of fluid inside tube with different temp. i successfully made region and run blockMesh, topoSet, splitMeshRegion, changeDictionary, but when ran chtMultiRegionFoam it gave this output in the log file.

Region: fluid Courant Number mean: 0 max: 0
Region: tube Diffusion Number mean: 1.1455094e-06 max: 2.0325246e-06
deltaT = 983.99791
End

this message appeared even i made the temp. of the two regions equal.

can any body help ??

Hi,

it is solved now it was issue of boundary conditions.

good day,
