This case could be too big to run with one process. Try to increase the number of processes or reduce the mesh size.

@Sushmitha46 I have checked and actually the plot3d writing does not work with the Intel compiler. The reason is the static declaration of grid3d. I pushed a change using allocatable memory which seems to me to fix the problem. Let us know if it's working for you now.

@francescosalvadore I tried to compile and run the new file, this time plot3dgrid was written but then same error followed, and I was not able to open the written plot3d files.

The below error was shown when I tried to open the generated plot3d file

@davidem88 I had previously tried to run it using 120 cores, it showed the same error.

@Sushmitha46, how is stacksize configured? Can you try to increase it (ulimit -s unlimited)?

[Sushmitha46]

I increased it and it worked. Thank you :)
