I am trying to find the area on a plane where a variable is above a certain value. Does anyone know a way to do this? Something like count the nodes or area on a certain plane if a variable is greater than some value?
Thanks in advance |

I think I figured out a way to do it.
1.) Plot the variable on the plane. For the variable range, make a "value list" of ranges. 2.) Make a "User surface" using the method "from contour" and choose the previously defined contour. Pick the contour level that corresponds to the correct range in the "value list" 3.) Use the function calculator to calculate "area" on the User Surface. I don't know how I figured that out... Rather complicated though, I wonder if there is a more elegant way than this? |

You are doing it in a manner that I would. I am unaware of any other way.

Create an "Iso Clip", select Location = Your Plane, and add a Visibility Parameter. For example, MyVariable >= 100
