danny123 Senior Member Daniel Witte Join Date: Nov 2011 Posts: 148 Rep Power: 14	Hi, I am trying to get the number of iterations of the matrix solver (e.g. PCG) back into the application solver, such as interFoam etc. I have looked at the code. In ldumatrix.H the iteration number is defined under solverPerformance. There are other values that I can get. If I call prghEq.residual(), I get the residual vector of the ldumatrix calculation. Is there some simple trick to get the iteration number? The iteration number of the matrix solver is printed out on screen, but this is done within a seperated routine (while the matrix solver is called). Regards, Daniel
