Hello!

I have following problem: My simulation of the internal flow of a nozzle shows proper results, but after running a certain time, this error will occur:

A floating point exception has occurred: floating point exception [Divide by zero]. The specific cause cannot be identified. Please refer to the troubleshooting section of the User's Guide.
Context: star.rsturb.RsTurbSolver
Command: RunSimulation
error: Server Error

I can restart the simulation again and it will run another few thousand iteration, but again this error will occur.

(simulation is unsteady and Reynoldsstress model is used. Decreasing the relaxation-factor for RS did not help)

Hope you can help me.

Have you tried running in double precision?
