Hello everyone,

while running a simulation I came across an error that I do not know what it means at all. Can anyone point me to the right direction?

The simulation is a simple square prism with water inside. The tank is set to oscillate left and right to simulate sloshing. The idea is to study how fluid behaves while sloshing. However I came across this error before the simulation can start.

another problem I am having is that I seem to be having an issue running simulations with multiple GPUs. Below lies my error that I am encountering.
Those simulation runs fine in series, however I am having issues running things parallel.
