Setting the inverse mass to zero (that is, infinite mass) on a fluid would causes infinite pressure to be applied. Obi check for this and freezes the particle in place, it shouldn't crash though. Can you share the editor crash log?

The proper way to do this is to convert the particle to a granular before giving it infinite mass. See:
http://obi.virtualmethodstudio.com/forum...-2849.html

Thank you for your very quick reply, I appreciate it.
I'll share the Editor.log with you, it contains excerpts from just before and after the crash.

Mesh 'Particle impostors': abnormal mesh bounds - most likely it has some invalid vertices (+/-inifinity or NANs) due to errors exporting.
Mesh bounds min=(nan, nan, nan), max=(nan, nan, nan). Please make sure the mesh is exported without any errors.

I also tried converting the particles to granular, but the crash still occurred.
Code:
for (int i = 0; i < emitter.solverIndices.Length; ++i){
int solverIndex = emitter.solverIndices[i];
emitter.solver.phases[solverIndex] &= (int)(~Oni.ParticleFlags.Fluid);
emitter.solver.invMasses[solverIndex] = 0;
}
