seltol#

Selecting.seltol(toler='', **kwargs)#

Sets the tolerance for subsequent select operations.

Mechanical APDL Command: SELTOL

Parameters:
tolerstr

Tolerance value. If blank, restores the default tolerance logic.

Notes

For selects based on non-integer numbers (e.g. coordinates, results, etc.), items within the range VMIN - Toler and VMAX + Toler are selected, where VMIN and VMAX are the range values input on the xSEL commands ( ASEL asel, ESEL esel, KSEL ksel, LSEL lsel, NSEL nsel, and VSEL vsel ).

The default tolerance logic 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).

This command is typically used when VMAX-VMIN is very large so that the computed default tolerance is therefore large and the xSEL commands selects more than what is desired.

Toler remains active until respecified by a subsequent seltol command. A seltol < blank > resets back to the default Toler logic.

Examples

Set selection tolarance to 1E-5

>>> seltol(1E-5)
