Mapdl.abs(ir='', ia='', name='', facta='', **kwargs)

Forms the absolute value of a variable.

APDL Command: ABS

  • ir – Arbitrary reference number assigned to the resulting variable (2 to NV [NUMVAR]). If this number is the same as for a previously defined variable, the previously defined variable will be overwritten with this result.

  • ia – Reference number of the variable to be operated on.

  • name – Thirty-two character name for identifying the variable on the printout and displays. Embedded blanks are compressed upon output.

  • facta – Scaling factor (positive or negative) applied to variable IA (defaults to 1.0).


The new variable is calculated as:

IR = | FACTA x IA |

For a complex number (a + ib), the absolute value is the magnitude, where the IA values are obtained from: sqrt(a**2 + b**2)
