CFD-post: defining (or projecting) point on surface

bongbang · March 31, 2015, 14:01

I'm making a time-series chart of wall shear stress at a point. I added the point using XYZ method and pointing the mouse at the location I wanted. I even looked at the point from different views to convince myself that it is where I think it is. When I turn on the chart, however, there is no WSS data associated with the point, which means the point is not on the wall (or, to be precise, the nearest node to the point is not on the wall). How can I define a point in such a way that ensures it's one the wall.

PS I tried defining the point so that is behind the wall (outside the fluid domain) in hope that the nearest node would be on the wall, but that didn't work either.

Problem solved. It wasn't what I thought it was, and defining a point on the wall is as easy as it should be.
