Good morning.

I´m making my first attempt with AEM3D.

After solve several problems and run the program, I found this error message (see below).

Can you help me?

Thanks in advance

It looks like your simulation may have gone unstable, if you are sure all your input bc data is OK then you may just need to reduce your timestep.
