to maybe catch an Exception which not belongs to the RuntimeException class. So far no success.
To be clear: The error still is null. Even though the try block seems to throw an Exception. I don’t understand how this can be.
However, reducing the runtime or node count drastically (1000 nodes or just 60mins runtime) seems to work.
The simulation then finishes withour any error. I am still interested in the results for 10000 nodes and a longer runtime though.
