Hello everyone,

I am a new user of OpenFoam solver. I am trying to practice some tutorials cases of OpenFoam and now I am running for a case of wigley hull form by using interFoam. With the data given by tutorials, it runs well. And Now I try to change grid topology from box grid of tutorial to O-O grid type by using Gridgen-Pointwise. I have also modified the boundary conditions of declarations with no sides boundary condition then run it. My grid is ok with checkMesh tool of openfoam. But when I run it, it show up error with time DelT becomes very small after short running time like this:

"Increased the timePrecision from 9 to 10 to distinguish between timeNames at time 0.000936731"

I think my setting up initial and boundary conditions are not good but I don't know how to do it?
Could you please guide me how to do it ?

Thanks a lot
