Hi
I ran the simulation included with the files "make fish swim". I increased the size of the background mesh, and inserted a different fish model. When it runs it exits without any error. Here is the output of the process: Code:

I see that the Courant number is large. I propose to decrease the initial time step and also reduce the Courant number max limit.
All the best Nikos |
