yeah had the same problem too, scaled the whole scene up by 2 and increased the resolution a bit and it worked again. my problem is the simulation does not "stick" to surfaces, so for cum it looks weird. well...maybe i just have to get the right settings to make it look a bit more realisticMight be worth some experiments.
I tried some blender fluid simulations but always seemed to run into problems if the domain was scaled too small.
