Disk actuator with only one side surface

[GovoniT]

Hi,

I was playing with the disk actuator model that is available in the RANS testcases, and I wanted to make my own mesh of the same test case geometry using gmsh. I was not able to generate a mesh with a surface that has two different distinct sides with different node indexes and markers in my mesh file. Thus since I had only a surface with "one side " I assumed that in this case, I had to change

ACTDISK_DOUBLE_SURFACE = YES

to

ACTDISK_DOUBLE_SURFACE = NO

And modify other parameters in the config files. So far, I tried many variations but none of them worked (divergence, or bad configuration of the .cfg file)

How to use correctly the disk actuator with this option set to no ? will the result be similar to the one with a two-sided disk?
