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: tetgen.exe -pq2 -A -n "C:\Users\Ana Paula\AppData\Roaming\isimpa\current\instance1\temp\scene_mesh.poly" 17:44:19: External code execution 17:44:19: meshing\tetgen\tetgen.exe -pq2 -A -n "C:\Users\Ana Paula\AppData\Roaming\isimpa\current\instance1\temp\scene_mesh.poly" 17:44:19: tetgen.exe : Opening C:\Users\Ana Paula\AppData\Roaming\isimpa\current\instance1\temp\scene_mesh.poly. tetgen.exe : Opening C:\Users\Ana Paula\AppData\Roaming\isimpa\current\instance1\temp\scene_mesh.var. tetgen.exe : Delaunizing vertices... tetgen.exe : Delaunay seconds: 0.002 tetgen.exe : Creating surface mesh ... tetgen.exe : Surface mesh seconds: 0.001 tetgen.exe : Constrained Delaunay... tetgen.exe : A self-intersection was detected.

Anyone knows what i can do? I need this with urgency :(
