I had that message the other day. I was examining flow (laminar, segregated, unsteady) around/though a porous medium and got that same message. I then tried starting out with very basic settings and working my way up to the values/properties I wanted.
For my specific case: I changed my porous medium to a solid and interface BC to walls, I found that that worked, then I changed my interface BC back to interface and changed the porous medium to a liquid. It continued to work then I changed the porous medium into a porous medium and I gradually increased the Resistance through the medium, and everything worked. I then tried re-initialize and ran the simulation and everything worked! Perhaps, I had overlooked something when I first set everything up and caught it when I tried a basic approach and worked my way back up. I don't know, I'm just happy it worked. Hope you find the problem, Tim. |
