Measuring Points in FEA
Measuring Points in FEA
(OP)
Hello,
I am trying to measure points on the attached design. It is a medical check valve that I applied a hydrostatic load to, in order to determine how much the valve would open up. I am attempting to estimate the area of the opening, so that I can perform further calculations.
I would like to measure the inside corners of the opening in XYZ coordinates, so that I can establish a rough estimate of the area of the valve opening. What is the best, and what is the easiest way to get those coordinates? I am using NX 7.5

Once you have a reasonable working analysis, getting the area of opening from the deflected shape should be quite straightforward - just plot the deflected coordinates as a 2D plot, and integrate under the curve to get the area.

so you know the distance between the four corners,
and you should be able to calculate a pretty close approximation for the opening area of each of the four triangle-ish areas ...
