Square pattern and stair-steping issue in Simulation

[sitnisati]

Hello,

I have checked the scene and this stepping is normal and unavoidable because FumeFX uses voxels for simulation and your mesh source is slightly sloped.
You could maybe smooth it out a bit if you set the object source type from solid to volume.

As for the flickering. I will sim it and render to see what happens.

Thank you.
