Negative initial temperature error
 

SonicFoam, k-epsilon model and snappyhexmesh is used for 3D geometry. No matter how to change the mesh number, maxCo and delta T, the error still exists. Temperature limit is added in fvOption, but it didn't work. Anyone knows how to fix the problem?

Hello keda,

does sonicFoam read the fvOptions file? You can check that at the begining
of the log file.

Otherwise check your boundary conditions and the mesh quality
(for this use the full check; checkMesh -allGeometry -allTopology)

Thanks, janibo. The problem is solved by changing the maxCo to 0.5 with more mesh.
