running bubble 3D test results in segafault

[fcannini]

Hi Ethan, how are you?

I've got back to the bubble_3D test problem of #1 and can't move forward. All other tests run just fine. ............................................................................................................ [user@machine bubble_3D]$ gdb --args ./runSimulation input_data ... [Thread debugging using libthread_db enabled] Using host libthread_db library "/usr/lib64/libthread_db.so.1".

It's weird that the code would segfault in that part, but I'm by no means knowledgeable in fortran. Any idea why is it happening?

TIA, Fabricio
