how to fix the error? #128

Closed gmcmtan closed 1 year ago

error I follow the tutorial to simulate the floating sphere. If I set the density of sphere to be less than 1000 Kg/m3, say 950, I will receive the error shown in the photo. And if I set the density to be greater than 1000, the simulation can be finished properly.

This happens because there are particles of the floating object that leave the domain due to their buoyancy when the density is less than 1000. You can define a larger domain in the +Z direction. In cases where the density of the object is greater than the fluid, the sphere is submerged and therefore, it does not leave the domain.
