nid${}_1$, nid${}_2$ Seed nodes
$\alpha_c$ Cut-off angle
default: $45^\circ$
Description

This command is used to define a surface from seed nodes with ID nid${}_1$ and nid${}_2$. nid${}_2$ only needs to be given if nid${}_1$ is located on an edge (see figure below). $\alpha_c$ is the angle between two faces that defines the boundary of the surface (default $\alpha_c = 45^\circ$).
