Hello everyone,

in the past, I had succeeded running a coupled eulerian lagrangian (CEL) method simulation using abaqus. Now I would like to run another CEL simulation, but something is going wrong and I could not find out what. The fluid, that is modelled as eulerian element, is flowing through the solid (lagrange element), although I have assigned a general contact interaction to it. I would be really grateful, if someone could give a look to the input file (1-CEL) and could give me a hint, how to avoid the leaking.

I also upload another input file (job-7d) containing a functioning CEL simulation.

Thank you everyone for any input.

Best regards,

Gunardi
