Hello foamers!

I'm using the chtMultiRegionSimpelFoamTensorK - Solver in
Version OF 2.1.1. My model is similar to the chtMultiRegionSimpleFoam Tutorial but it is a little more complex.
I have two fluids (air and water) and a couple of solids.

When starting the Solver, there is the error:



*** Reading fluid mesh thermophysical properties for region fl_luft

Floating exception



The thermoPhysicalProperties are the same as in the Tutorial. The Tutorial runs without a Problem.
Can this error be because of a bad mesh?

Best Regards and thanks !

Hello Oli,

Foam::sigFpe means that you are somewhere dividing by zero.

Check the boundary conditions for the turbulent kinetic energy. If it's set to 0 just change it to 1e-10 or something like that.
But I don't know, this error can be due to many other things too..

Hope it helped!

Hello Ignacio,

thanky you for the quick answer.
Unfortunatley its not the turbulent kinetic energy.
There is no 0 in it.

Best regards

hello! were you able to solve your problem?
I'm trying to run chtMultiRegionSimpleFoam with water and can't set properly water properties.
