nailedit Posted December 14, 2017 Share Posted December 14, 2017 (edited) Hi So I want to make the smoke fill the spiral tube and I'm pretty close to result I've been aiming for but i've run into a problem I can't seem to resolve. At one point in the simulation smoke stops responding to forces and just follows the tube (attachment). My process of making this set up: 1. convert tube to volume 2. attract billowy smoke emitted from sphere to the volume tube (attract fluid) 3. add a curve force (curve was used to make the tube so it is in the middle of the tube) I've tried changing every paramiter I could think of but nothing helped. Anyone has any ideas? Smoke preview youtube Smoke_problem.mp4 Edited December 14, 2017 by nailedit Quote Link to comment Share on other sites More sharing options...
lukeiamyourfather Posted December 15, 2017 Share Posted December 15, 2017 Do the values go negative and get clamped or something along those lines? It looks like it crosses and axis when it stops working. Without the scene file it's hard to say. Quote Link to comment Share on other sites More sharing options...
nailedit Posted December 15, 2017 Author Share Posted December 15, 2017 Unfortunately this didn't fix it, the reason I didn't post the file is becouse I exported the tube and curve from Maya so not really sure if this will work if I just post the FBX and file, but worth giving a shot now that I think about it.

Atom Posted December 15, 2017 Share Posted December 15, 2017 Try disconnecting the Resize from the solver. You don't really need it. The resize is not configured correctly and ends up clipping the results. Quote Link to comment Share on other sites More sharing options...

Atom Posted December 15, 2017 Share Posted December 15, 2017 (edited) It worked for me. Did you rewind and clear the broken/previous cache? Edited December 15, 2017 by Atom Quote Link to comment Share on other sites More sharing options...

I ran the sim twice, both times problem wasn't fixed :/ weird that it fixed it for you, can I see your file? Quote Link to comment Share on other sites More sharing options...
Noobini Posted December 15, 2017 Share Posted December 15, 2017 you'd think it's the curveforce...but no...disabling it still gets you the same effect (NO effect after a certain distancce that is)... It has something to do with the size of your sphere1, ie. uniformsdale to 0.5 and you'll see immediately the NON-effect kicks in SOONER...make it larger and the non-effect will be later....

Noobini Posted December 15, 2017 Share Posted December 15, 2017 ok, here's my attempts...in pyrosolver>shape>disturbance, I cranked the hell up of everything... - Cutoff: 10.1 - Control Influence: 10 - control range: 10.05 but only you would know if this has the desired effects.... 1 Quote Link to comment Share on other sites More sharing options...

I'm caching the scaled sphere sim now, i'll try this after and let you know how did it go, whatever the result, thank you for the help.

nailedit Posted December 16, 2017 Author Share Posted December 16, 2017 Changing the Disturbance setting did help, altho the turbulance still isn't there and if I try to tweak those same settings for turbulance(even with lower values), the smoke just goes crazy, I'll try a some more tommorow but right now it's 2am so I guess some sleep would be a nice idea. Once again thanks for all the help. Quote Link to comment Share on other sites More sharing options...
