Model.hmmeshsurfacesphere

Model.hmmeshsurfacesphere(quads)

Within the automeshing module, generates quad or tria elements using a surfaceless algorithm. Can only be used with model.surfacemode(mode=3) and one of the Model.surfacespherefromfournodes() or Model.surfacespherefromthreepoints() or Model.surfacespherefull() function.

Parameters:

quads (int) – If nonzero, specifies that the created elements should be quads.

Example

Identify a spherical region pass through the given four nodes , and , without actually build a surface , creates 150 elements with a density of 15.0 along a longitude and 10.0 around the equator

model = hm.Model()
