I am trying to model a sloshing liquid tank.
I have modeled a rectangular tank with a unit thickness. the side and bottom faces are wall with specified mesh displacement (Asinwt). and the top is opening BC.
It runs well with homogeneous but when I uncheck homogeneous to have inhomogeneous, after a couple of iterations i get overflow error.
How can I solve this?

In cfx-pre I also have this message :"In Analysis 'Flow Analysis 1': Export results are unavailable as no suitable boundaries exist for use as export surfaces. Mesh motion on a boundary invalidates its use as an export surface." what does it mean? is it important?

thanks

Hi dear hamed
I'm a hydraulic structure student of Tarbia Modares of Tehran.
I had a similar problem. But there's not any problem. It's not an error, it's just a warning.
I have some problem at the next steps of the problem. If you want I'll be happy to your synergy.
