i have opend a calculate in Star CD, but it calculates always to the same time step. Then it does not go ahead. But it seems still well. Like this:

FINISH TIME STEP NO. 1687
CPU TIME IS 1460.37 ELAPSED TIME IS 1637.06 MEMORY (DYNAMIC) USED IS 1738 MBYTES

I am not sure what I am looking at here, the output of the run file or the info file.

However, not knowing something will not keep me from trying an answer. Usually in STAR-CD if the run stops it is for one of three reasons: 1) an error occurred, 2) you have reached the maximum number of iterations specified, or, 3) you have reached your tolerance on the residuals. Since there is no error message given, I would investigate nos. 2 & 3.
