Hello everyone,

I am working on a improved version of the waveFlume to study the free surface elevation of an oscillating water columns. I created the device with FreeCad and I generated the mesh with SnappyHexMesh.

I am running my model in parallel with a cluster. All the first step which initialise the model work well but when I start the first iteration, they stop after 5 sec because of a segmentation fault. I am still a new user of waves2Foam and I would like to know what what can be the origin of this problem.

Here is my error message:

Good morning

@Olivier: Something is wrong with your surface elevation extraction at run-time. At least that is where the code fails. Check the validity of the wave gauges.

Kind regards,
