AlbusNolente Posted March 3, 2020 Share Posted March 3, 2020 Hi there, So basically I have this exhaust smoke sim coming out from a flying drone. I would like the end of the smoke trail to dissolve nicely like it happens in the real world. In my sim this doesn't happen because the trail after 33 frames starts to be cut by the bounding box in a “sharp” way as you can see from the pictures. Unfortunately, I can't share the scene but let me know if you need more information. The solvers's shape settings are: dissipation 0.08, disturbance 6, shredding 0.05, sharpening 0.5, turbulence 0.15. Thanks. Quote Link to comment Share on other sites More sharing options...
evanrudefx Posted March 3, 2020 Share Posted March 3, 2020 hey, it seems like you have a problem with your gas resize node (I am assuming its not sparse). If you go to max bounds on the gas resize fluid dynamic node, make sure clamp to maximum is unchecked. Also in the "bounds" section, you may need to lower the field cutoff value.

Atom Posted March 3, 2020 Share Posted March 3, 2020 Set Dissipation way higher. Try like 0.98 and then drop it down toward zero. Quote Link to comment Share on other sites More sharing options...
