@skhayrulin I added a test for the cube with membranes and water inside. The test is crashing the kernel (the one without water works fine). This is what gets printed in the console

Can you try and see if it works in yours? Also I commented testSolve14_ExpectNaN and testSolve216_NaN in PCISPHSolverTest as they were both crashing and would prevent mvn install to finish. Can you uncomment them locally and see if they pass in your system? Every other test in PCISPHSolverTest works.

@skhayrulin run the liquid test on Sibernetic and it seems to work there. Next step is to realize what is different with the porting.

Test report with latest membranePorting:
All checkpoint fail and should be fixed.
When running with the frontend the liquid scene explodes on my Mac (both CPU and GPU):
The new added test cube with water passes on my CPU but not on GPU, every other test works fine on mine GPU.
When running with the frontend the cube with water scene (using the CPU as the GPU gives a seg error) the scene disintegrates into tiny dots.
I will try next to run on Amazon to see what from the above is different in terms of explosions and tests passing/failing.

@dkruchinin glad you don't see the segmentation fault when running those tests. This is the other issue that I was having on my mac that doesn't seem to happen on Linux. Basically while using the membranePorting branch try loading the liquid simulation sample and see if the liquid for you explodes like in the screenshot above. I am tracking this issue here
