Step-by-Step Tutorial: Homework of Session 4

Greetings,

Has someone arrived to a solution to this simulation run error?:
“The job execution was aborted, possibly due to a numerical instability. Review the log to identify reasons: unphysically large field values, extremely small time step size, etc. Modifying numerical settings and time step size could resolve the issue.”

My simulation has now failed three times in a row after following the tutorial correctly and the deadline for the homework is in one day.

Here is a link to my project:

Best regards.
