I have attached the 3D data set. I have generated the small data for the testing.
ex, ey and ez are the coordinate points in x, y and z direction.
I want to select points in semi circular pattern. Attacehd is the picture.
x = horizontal
z = vertical
y = 3rd dimention i.e. width
I am also facing problem to visualise the data in 3D. How to see the selected elements in 3D inside rectangular region.
Attached is the figure of the model. i want to create the semi elliptical notch.
If one can provide to generate the mesh for this block is also welcome.
for 2D i used inpolygon to extract the points.
