RealFlow Official Forum

I am attempting to make a simulation with a very thick goo and I wanted to tap the knowledge of the forum for advice as I experiment.

The goal : have a sphere of "goo" fall onto complex geo. The goo is moving fast and on impact explodes a bit, with big goopy tendrils that are pretty strongly connected and swing down and stick to the complex surface. Think of it like a slimy taffy.

My first attempts have been using a high viscosity setting and a high surface tension, and it is a bit goopy, but it really falls apart on impact. What force or attribute would make the goo "want" to stay together? To get nice long tendrils. What would make it sticky? There is a stickiness setting on the objects but not one on the emitter.

Any advice would be appreciated.

Hi Chris,

I'd recommend cranking up the viscosity and sticky settings quite a bit, and also reducing internal pressure, maybe even increasing the external a bit, to maintain the fluid together. It really depends on the scale of the sim and what exactly are you trying to achieve, but you are in the right track.
Take out the bounce from the geometry if you want to reduce the impact forces and make it more sticky.
