rzst

 

Generates points on the surface of spheres or parts of spheres defined by the input parameters. The resultant point distribution should produce similar sized triangular faces. The surfaces are defined with spherical coordinates (r,theta,phi).

rzst / nr, ntheta, nphi / rmin, thetamin, phimin / rmax, thetamax, phimax / xcen, ycen, zcen / irz, itz, ipz / irratio, itratio, ipratio / rrz, rtz, rpz

Parameters

Type/Value

Description/Default

add

add

Find the intersection of mesh1 and mesh2. Refine mesh1 where it overlaps mesh2 based on the refine_factor. After the refine steps have been done, the intersection of mesh1 and mesh2 is found, elements that overlap are deleted from mesh1 and mesh2 is appended to mesh1 to create mesh3.

Parameter
