*surfacespherefromfournodes

Creates a sphere which passes through the four specified nodes, and optionally, prepares it for immediate use within the automesher. It can also identify a region in the shape of such a sphere for the automesher to use under the mesh without surface option.

Syntax

*surfacespherefromfournodes list

Type

HyperMesh Tcl Modify

Description

Creates a sphere which passes through the four specified nodes, and optionally, prepares it for immediate use within the automesher. It can also identify a region in the shape of such a sphere for the automesher to use under the mesh without surface option.

Inputs

list
The list of the four nodes through which the surface will pass.

Example

To create a sphere which passes through nodes 1, 2, 3, and 4, but not create any elements on the sphere:

*surfacemode(4)
*createlist(nodes,1) 1 2 3 4
*surfacespherefromfournodes(1)

*createlist() is required for this command. The *surfacemode(4) directive tells HyperMesh not to pass the information on to the automesher for element creation.

Errors

None.
