TAGGED: dpm, pressure, wall-roughness
May 31, 2022 at 5:24 amNargesSubscriberHello there. I have a nanoparticle injection to water flow colliding a wall with 2micron roughness. I wonder if the surface roughness has an effect on "DPM Wall Normal Pressure" ?
May 31, 2022 at 8:31 amNargesSubscriberin fact I want to know if the calculated Normal Pressure is normal to the wall or to the wall roughness. I will appreciate it if anyone can help. I couldn't find the answer in Ansys theory guide.

It'll probably be normal to the wall facet. Roughness is typically used for turbulence.
