warning
 

I am simulating the dike in the flume and I have got the below warning. Can anybody has the idea about it?



============= mentor tip ===============
pressure iterations limiting time step.
1. check for poor mesh aspect ratios.
2. use ADI or GMRES solver.
3. try autot=2.0.
4. increase convergence tolerance epsi.
5. if nmat=1, try some compressibility
by setting rcsql > 0.
6. increase restart number for GMRES.
7. reduce alphamb for multi-block cases.
