Mapdl.hptcreate(type_='', entity='', nhp='', label='', val1='', val2='', val3='', **kwargs)#

Defines a hard point.

Mechanical APDL Command: HPTCREATE

Parameters:
type_str

Type of entity on which the hard point will be created.

  • LINE - Hard point will be created on a line.

  • AREA - Hard point will be created within an area (not on the boundaries).

entitystr

Number of the line or area on which the hard point will be created.

nhpstr

Number assigned to the hard point. Defaults to the lowest available hard point number.

labelstr

If LABEL = COORD, VAL1, VAL2, and VAL3 are the respective global X, Y, and Z coordinates. If LABEL = RATIO, VAL 1 is the parameter value (this is available only for lines). Valid parameter values are between 0 and 1. VAL2 and VAL3 are ignored.

val1str

If LABEL = RATIO, ratio value for line. If LABEL = COORD, global X coordinate value.

val2str

If LABEL = COORD, global Y coordinate value.

val3str

If LABEL = COORD, global Z coordinate value.

Notes

The ability to enter a parameter value provides a simple way of positioning hard points on lines. For example, to place a hard point halfway along a line, one can simply specify a VAL1 value of 0.5.

For models imported through the DEFAULT IGES filter, you can place hard points on models only by specifying coordinates (you can’t place a hard point using interactive picking).

If you issue any commands that update the geometry of an entity, such as Boolean or simplification commands, any hard points associated with that entity are deleted. Therefore, you should add any hard points after completing the solid model. If you delete an entity that has associated hard points, those hard points are either

  • Deleted along with the entity (if the hard point is not associated with any other entities).

  • Detached from the deleted entity (if the hard point is associated with additional entities).

When archiving your model ( cdwrite ), hardpoint information cannot be written to the IGES file. The Jobname.cdb file can be written with the cdwrite,DB option.

Hard points are only applicable for area and volume meshing, not for beams.
