There are several options you can use to eliminate such artifacts.
Grid Resolution
First, make sure your grid resolution is not too low. If you have a simulation with less than 10 milliоn voxels, the flickering might be resolved by increasing the grid resolution and simulating again.
Render-time Solutions
There are also many ways to reduce or completely resolve such flickering after the simulation is done, without having to simulate all over again.
...
- [Mesh and Isosurface] changing the Isosurface Level option;
- [Isosurface only] changing the Isosurface Sampler from Linear to Spherical;
- [Mesh and Isosurface] enabling Input Grid Channel Smoothing;
- [Mesh only] enabling Mesh Smoothness and optionally enabling the Use Liquid Particles option;
- [Mesh only] adding a Relax modifier;
Isosurface Level
Changing the Isosurface Level would help when in animation you see many pairs of droplets that keep connecting and disconnecting from one another.
...
Note that if you go with too low or too high Isosurface Level, the liquid will either shrink too much or the opposite - gain too much volume and become too chunky.
Isosurface Sampler
Changing the Isosurface Sampler from Linear to Spherical can help in case after switching from Mesh to Isosurface mode, some droplets don't look round enough and are still somewhat edgy.
This will smooth these droplets additionally at the expense of some rendering slowdown.
Grid Channel Smoothing
Input Grid Channel Smoothing will work for both Isosurface and Mesh modes in order to reduce flickering in animation.
...
The recommended values for the smoothest result are all zeroes for the Threshold, Similarity and Random Variation options - this will produce strongest smoothing, evenly applied over the entire liquid grid evenly, without adding any random variation.
Mesh Smoothing
When rendering in Mesh mode, you have additional control allowing you to smooth out the produced mesh surface.
...
This can also improve any flickering in animation. Note that Mesh Smoothness can be used together with Input Grid Channel Smoothing.
Relax modifier
An additional tool you can use for further smoothing the mesh surface would be the 3ds Max Relax modifier. It can also be combined with Grid Channel Smoothing and Mesh Smoothing.
