Hi, guys~ This time I made some smoke in the tube and the tube with a little shape animation. But the tube leaked smoke.
I tried to increase “steps per frame”. The smoke still leaked… How to solve this problem ? Thank you for your kind reply.
Hey,
Please put a shell modifier on the pipe and make sure to adjust the pipe wall thickness and the simulator grid resolution so the pipe wall is at least two voxels thick.
Cheers!
