LUDecomp: SINGULAR MATRIX

Post by Andrea_P »

Good morning dear community,
I am trying to run this case (attached case.sif and mesh), nevertheless, it always produces the same error message: "LUDecomp: Matrix is singular". I do not know how to fix this problem. The aim is to observe the fluid interface moves along the moving wall towards the outlet. Any suggestions will be welcome.
Thanks for your answers.
Regards,
Andrea
