Hello,

I have a problem with my simulation. It is a problem others had too but I don’t know how they fixed it.  
There is an Error and it says:  
“The job execution was aborted, possibly due to a numerical instability. Review the log to identify reasons: nonphysically large field values, extremely small time step size, etc. Modifying numerical settings and time step size could resolve the issue.”  
Could someone tell me how i can fix that?

Thank you

Hi @sliu!

As mentioned in the other thread make sure you counter-check every parameter from the step-by-step tutorial and mesh your front wing properly in order to avoid mistakes.

Best,

Jousef
