I am quite new to openfoam, I changd the simpleFoam to create a solver which adds diffusive mass transport into it....but the process fails and stops after t=4, can u pls tell me what this error message is all abt and a possible solution as well??? PLS!!!!

small correction, it doesn't actually fail, it runs, but stops at t=4, everytime....
