Dear all,

i encountered a error message claiming my integer stack memory is insufficient.

What i don't understand is: i was running the simulation with 30000000+ elements without this error message, but after reducing the mesh to about 20000000+, and this error occurs.

Does it indicate there's something wrong with my model please?
Below is part of the monitor log where the error message is prompted:

You just need to make the integer stack bigger. Have a look in the documentation for how to do this.
