Hello.
my model in cfx is ok in tmesteps over 0.025 second but it doesn't run in timestep lower than 0.025 and get an error. Do you know why? |

Most likely this is due to numerical round off problems. If you run double precision you should be able to fix this.
Also improved mesh quality and initial conditions can assist. |
