ekill

Mapdl.ekill(elem='', **kwargs)

Deactivates an element (for the birth and death capability).

APDL Command: EKILL

Parameters
elem

Element to be deactivated. If ALL, deactivate all selected elements [ESEL]. A component name may also be substituted for ELEM.

Notes

Deactivates the specified element when the birth and death capability is being used. A deactivated element remains in the model but contributes a near-zero stiffness (or conductivity, etc.) value (ESTIF) to the overall matrix. Any solution-dependent state variables (such as stress, plastic strain, creep strain, etc.) are set to zero. Deactivated elements contribute nothing to the overall mass (or capacitance, etc.) matrix.

The element can be reactivated with the EALIVE command.

ANSYS, Inc. recommends using element deactivation/reactivation (EKILL/EALIVE) for linear elastic materials only. For all other materials, validate the results carefully before using them.

This command is also valid in PREP7.
