BND_disk

create a disk

A disk can be defined by:
begin_boundary_elements{} BND_disk &aliasDefinition& x0 y0 z0 nx ny nz radius OPTIONAL:NumberOfSegmentsInCircle end_boundary_elements
The disk is given by the center point (x0,y0,z0), the direction of the axis (nx,ny,nz), and the radius. NumberOfSegmentsInCircle defines the number of discretization ticks for the circle. By default is 51.
