Creating a Surface Given a Surface Normal

Coreform Cubit Creation and Modification

Is there a way in Cubit to create a surface given a vertex and a known surface normal?

#2

We do have commands in cubit to generate a plane without defining the boundary. They will clip the plane to the bounding box of one or more volumes (bodies).

Create Planar Surface [With] Plane Vertex <v1_id> [Vertex] <v2_id> [Vertex] <v3_id> [Intersecting] Body <id_range>] [Extended Percentage|Absolute ]

Create Planar Surface [With] Plane Surface <surface_id> [Intersecting] Body <id_range>] [Extended Percentage|Absolute ]

Create Planar Surface [With] Plane {Xplane|Yplane|Zplane} [Offset ] [Intersecting] Body <id_range>] [Extended Percentage|Absolute ]

Create Planar Surface [With] Plane Normal To Curve <curve_id>{Fraction | Distance | Position | Close_to vertex <vertex_id>} [[From] Vertex <vertex_id> (optional for ‘fraction’ & ‘distance’)] [Intersecting] Body <id_range>] [Extended Percentage|Absolute ]

Unfortunately I don’t see a method for building the surface from a point and a normal. This should be something easy to add to cubit. We can add a feature request if you want.

You could create a surface normal to plane. In the GUI Geometry/Curve/Create/Planar Surface

The command is of the form:

create planar surface with plane normal to curve 1 close_to vertex 1

Note that you will have to create a curve defining the normal.
