Hi,
I am running a free surface simulation on a wigley hull, I run the Solver and after 30 iterations it stops with an error. The simulation progresses quite well other than the exit error. Does anyone have any suggestion? Below is a part from the output file: OUTER LOOP ITERATION = 31 CPU SECONDS = 9.03E+03 ---------------------------------------------------------------------- | Equation | Rate | RMS Res | Max Res | Linear Solution | +----------------------+------+---------+---------+------------------+ | U-Mom-Bulk | 0.99 | 4.6E-03 | 2.5E-01 | 3.7E-04 OK| | V-Mom-Bulk | 1.01 | 1.2E-04 | 4.0E-03 | 3.3E-02 OK| | W-Mom-Bulk | 0.98 | 2.0E-03 | 3.3E-02 | 5.5E-04 OK| | P-Vol | 0.98 | 1.7E-05 | 9.1E-04 | 9.1 6.0E-02 OK| +----------------------+------+---------+---------+------------------+ | Mass-Water at 25 C | 1.00 | 7.0E-02 | 9.8E-01 | 10.4 5.3E-17 OK| +----------------------+------+---------+---------+------------------+ | K-TurbKE-Bulk | 0.95 | 4.6E-03 | 1.7E-01 | 10.3 3.7E-08 OK| | E-Diss.K-Bulk | 0.96 | 2.8E-03 | 2.4E-01 | 11.1 5.0E-08 OK| +----------------------+------+---------+---------+------------------+ Execution terminating: STP file found.
