purple.monkey is on a distinguished road
Hi all,

I would like to use the actuator disk model to simulate a pressure loss (e.g., simulating a wind turbine instead of a propeller), but the current implementation appears to only be valid for the case of a pressure rise. At least, any case I try to run with a pressure loss (putting a negative value in MARKER_ACTDISK) diverges.

Going through the streamtube analysis and theory of actuator disks, it seems like it should just be a few sign changes to handle a pressure loss instead of a rise, but I can't seem to find where in SU2 those sign changes need to be made.

Can someone who is familiar with the actuator disk implementation provide some help, please?

Thanks in advance for any help/tips!
