hello , it is probably a noob question but i need to learn it anyway . so i am trying to make cartoonish fire but normals ruin a bit of pyrosolvers' settings . the best way to explain what i am asking is a secreen shot and some arrows inside of it

basicly i want fires to came out from only one side , not both sides of grid .

i want blue ones , not red ones . are there any way to turn of red side or should i try another methods inside pyrosolver ?
Thanks !

They are actually moving in the right direction of the velocity. It looks like maybe you don't like how the source is extending a bit out past your emitter. That would be because your source settings arent trimmed down far enough to encompass just the source particles. You can put a collision object, like a wall on that side, and the pyro will not go in that direction, and anything inside will get cropped when the sim starts.
