Justin K 9 Posted April 11, 2019 Hey! Can anyone explain the difference between these two approaches when applying velocity fields to a pyro sim? Example 1: sop vector field piped into a field force after the pyro solver itself Example 2: Same sop vector field imported into dops using a source volume dop. Volume is called force. This volume is called in a gas advect dop --piped into the advect input of the pyro solver itself. Im having issues with method 2. Overall I am trying to make a pyro sim narrower--and am using a custom velocity vector field to try and force the gas to stay more compressed, but I cant get convincing interaction with the divergence stage of the sim. I had been trying the gas advect for a while, but now Im trying the example 1 approach. I was curious as to whether or not the field force would work better because it is actually operating independent of the pyro solver with its nondivergent stage . Thanks!
