I have a 3D model in comsol (Please, find the attached comsol model). I want to get the x, y and z coordinates of the model. And I want to use the z coordinate as design variable. the ultimate goal is this: As I vary each of the z coordinates of the model, I want the topography of the model to change. How can I achieve this? Alternatively, how can I create points on the 3D model such that as I varies the z-coordinate of each of the points, the topography of the model associated with that point will also change?
Not exactly sure what you are trying to do.
If you want to change the topology in the sense that you want to add noise to it (intuitively speaking, you want to ruffle up the surface), then you could look into Perlin noise, which will help you distort your surface.
If its a requirement to use the z component of your control points as an input for how much "ruffling" is done to the surface, you'd have to map the z component into the input space of the perlin noise function. (i.e, map your z values from [min,max] -> [0, 1] ) and then use this as a weight applied to the output of the perlin noise.
Perlin noise basically is good for smooth randomness, (as often encountered in nature)
Obviously you'd have to do some programming to get it done.
Hope that helps.
