we haven’t tried, but it should be possible
Cohesion(surface tension)/adhesion forces are possible (used for example for honey or mercury in “various materials”). The only non-newtonian viscosity we tried was used for sand. I’ve seen some (real) videos of various weird non-newtonian fluids, I would need to see a mathematical description of that behavior to see if it’s possible to simulate in our framework.
We are working on it, we release videos, when we are happy with the quality.
