Hi @michael.komm and welcome to the FESTIM discourse!

First up, when asking a question about an error message, it is essential to provide the _full_ error message otherwise it’s very hard for us to assist. [Read before posting: How do I get my question answered?](https://festim.discourse.group/t/read-before-posting-how-do-i-get-my-question-answered/121)

FESTIM can “crash” in different ways.

It can be that the mesh needs to be more refined near the implantation zone, or the tolerances need to be tweaked… I can’t really say more at this stage
