hello guys,

In <.info> file the error is shown(cell center outside of cell for cell no. 1 etc).But in check evrything no error is shown. Will it have any bad impact?

Thanks in advance

Hi, To me it seems that the mesh is not proper. Check all the cells for centroidal check using check tool option. Try to reduce the skewness of the grid by remeshing or by hand fixing. The exact impact on the solution for this grid cannot be predicted. Till the point you are getting converged solution, check the accuracy with benchmark. Try also increasing the convergence criteriorn. If your grid is good the decrease in convergence criteriorn should not change the solution significantly if the grid is good.
