Hi all, I am trying to simulate a dam break with sloping sea wall using the compressibleMultiphaseInterFoam solver. After running blockMesh and setFields, I get this error when compressibleMultiphaseInterFoam is running:

Aborted (core dumped) I've checked the boundary conditions and they all seem fine. Could use some help, thank you. https://drive.google.com/file/d/15Im...ew?usp=sharing Here's a link to download my case for more information. |
