WebMay 25, 2014 · There are some possible reasons you are getting pressure iteration failures: 1) the mesh aspect ratio is not good. Look at the ratio between cell size in Z and cell size in X: it should be <3:1 (big:small), otherwise the calculations are stretched and hard for the computer. The best ratio is 1:1 (squares). http://www.feflow.info/html/help72/feflow/09_Parameters/Boundary_Conditions/boundaryconditions.html
