Hi everyone!
I'm working on a simulation of membrane-based filtration, but recently encountered a big difficulty. I'm eager to get any guidance.
The physical problem shown in FIG: The computing domain consists of two different fluid zones
Encountering problem: After initializing the case and loading UDF, I run it and got a error report: 1) Divergence detected in AMG solver: momentum, pressure correction, and species. 2) Error at host: floating point exception. and 3) Error at Node: floating point exception.
