Noob here, in learning phase.
just sucessfully compleated incompressible fluid car aerodynamic tutorial and wanted to try something similar.
imported my simple 3d model, created enclosure, created new simulation.
while assigning material ‘air’, i cant see ‘flow region’. instead, it is automatically assigning air material to my model
what am i doing wrong?
any direct help/reference link is highly appriciated
reference image (if it helps):
