I solved the problem changing from steadyState to Euler (on fvSchemes).


Now it is:


ddtSchemes
{
default Euler;
}

Hi, I'm getting similar error. I've tried a lot of things but i didn't solve my problem. My solver is interFoam. Just look at deltaT and alpha.water values in error file. How can i fix this? Any suggestion?
(I used SolidWorks 2016, salome 8.4.0, openfoam-7, ubuntu 18.04 and i customized classic laminar/damBreak case.)
