|Summary||0001971: Possible bug in the use of transonic in twoPhaseEulerFoam|
|Description||When transonic is enabled in twoPhaseEulerFoam, |
It showed the error message for all cases tested and tutorials.
--> FOAM FATAL ERROR:
cannot scale a matrix containing a faceFluxCorrection
From function fvMatrix<Type>::operator*=(const DimensionedField<scalar, volMesh>&)
in file src/finiteVolume/lnInclude/fvMatrix.C, at line 1220.
I don't know, but this looks like a bug to me.

||Which version of OpenFOAM are you running and have you also tested reactingTwoPhaseEulerFoam which will replace twoPhaseEulerFoam after it is fully validated.|
I tested versions 2.3.1 and 3.0.1.
I didn't test reactingTwoPhaseEulerFoam. I'll test!
||I have some thoughts on this. What we need is a suitable test-case (small-ish, 2D) which is transonic with a modest max Mach number; do you have something like this setup? What twoPhaseEulerFoam cases are you running which need transonic support in the pressure equation?|
I am simulating a tube rupture of a industrial heat exchanger, the tube pressure is 88 bar and shell side has a pressure of 1 bar. The tube has natural gas and shell has thermal oil.
About the test-case 2D...
I guess so, before, i had tested a case 2D with VOF.
Mesh made by blockMesh, 90000 cells, setup with the above described values, basically.
Within a certain time of simulation, the Mach number was less than 0.5.
||If you can provide a suitable 2D test-case, ideally smaller than 90000 cells I will investigate this further.|
||Resolved in OpenFOAM-dev by commit 7f67b3e46e6b2114db8ba7c5b863ae509797b430|
