*scalemarkwithsystem

Syntax

*scalemarkwithsystem entity_type mark_id scale_x scale_y scale_z system_id origin

Type

HyperMesh Tcl Modify Command

Description

This command scales a selection of entities by multiplying the coordinates.

Inputs

entity_type

The type of entity to translate.

mark_id

The ID of the mark containing the entities. Valid values are 1 and 2.

scale_x

The multiplication factor for the x-axis of the system.

scale_y

The multiplication factor for the y-axis of the system. Only used in rectangular coordinate systems.

scale_z

The multiplication factor for the z-axis of the system. Not used in spherical coordinate systems.

system_id

The ID of the system which the scaling is in relation to. Note that the type of system affects the scaling. For example, specifying scale_x in a cylindrical or spherical coordinate system scales the mark radially out from the origin.

For scaling of rigid walls in the rigid wall local system, specify as 0.

origin

If zero, the scaling is based at the origin of the system. Otherwise, it specifies a node ID whose coordinates define the base point of the scaling.

For scaling of rigid walls in the rigid wall local system, specify as 0.

Example

To scale nodes 1-8 5 units in the x-direction of system 13 with node 20 as the origin:

*createmark nodes 1 1-8
*scalemarkwithsystem nodes 1 5.0 1.0 1.0 13 20

To scale the rigid wall rwcyl relative to the rigid wall local system:

*createmark groups 1 rwcyl
*scalemarkwithsystem groups 1 3.0 1.0 1.0 0 0
