Problem with I SIMPA'S SPPS calculation

[anabragad]

I imported a model, remeshed it, and set up sources/receivers, then ran calculation SPPS. I followed the guidelines provided in the under Tutorials. The console reads as follows:

17:44:19: Scene repair complete
17:44:19: Meshing with the following parameters:
