Hello all

I'm trying to make a simple 2D injection simulation into a circular combustion chamber. The chamber is pre-filled with air and it consists only of an inlet in the top of the circular walls and a spark plug.

I tried to set up multiple injection parameters but none seem to work: single injection, group injection, surface injection... It is as if there was nothing being injected.

I just want to simulate a "pulse" of fuel getting into the chamber, but I don't know why I'm not able to. Is there something I'm missing? Is there another way to do it?

Thank you
