Hello!

I'm having the problem that sometimes when I reduce the particle separation in my particle fluid object (particle count ~2000), the particles completely disappear when I start the simulation and it doesn't do any calculations.
Increasing the separation and thus reducing the particle count makes the simulation work again.

I'm using rather high gas constant and viscosity values: gas constant = 10000 - viscosity = 100.
No other forces are used.

What causes this and how can I fix it?
Does it have something to with the simulation exploding from too high forces?

How can I fix it and how can I exactly measure the particle count of my particle fluid object?

Thanks!
