Mapdl.ksel(type_='', item='', comp='', vmin='', vmax='', vinc='', kabs='', **kwargs)

Selects a subset of keypoints or hard points.

APDL Command: KSEL


Label identifying the type of select:

S - Select a new set (default).

R - Reselect a set from the current set.

A - Additionally select a set and extend the current set.

U - Unselect a set from the current set.

ALL - Restore the full set.

NONE - Unselect the full set.

INVE - Invert the current set (selected becomes unselected and vice versa).

STAT - Display the current select status.


Selects a subset of keypoints or hard points. For example, to select a new set of keypoints based on keypoint numbers 1 through 7, use

>>> mapdl.ksel('S', 'KP', '', 1, 7)

The selected subset is used when the ALL label is entered (or implied) on other commands, such as KLIST,ALL. Only data identified by keypoint number are selected. Data are flagged as selected and unselected; no data are actually deleted from the database.

This command is valid in any processor.

For selections based on non-integer numbers (coordinates, results, etc.), items that are within the range VMIN -Toler and VMAX + Toler are selected. The default tolerance Toler is based on the relative values of VMIN and VMAX as follows:

If VMIN = VMAX, Toler = 0.005 x VMIN.

If VMIN = VMAX = 0.0, Toler = 1.0E-6.

If VMAX ≠ VMIN, Toler = 1.0E-8 x (VMAX - VMIN).

Use the SELTOL command to override this default and specify Toler explicitly.

To select a single keypoint (keypoint 1)
