etcontrol

Mapdl.etcontrol(eltech='', eldegene='', **kwargs)

Control the element technologies used in element formulation (for applicable elements).

APDL Command: ETCONTROL

Parameters
eltech

Element technology control. One of the following:

  • "SUGGESTION" : The program offers a suggestion for the best element technology before solving. If necessary, mixed u-P (KEYOPT(6)) is also included and reset. This behavior is the default.

  • "SET" : The program informs you of the best settings and resets any applicable KEYOPT settings automatically. This action overrides any previous manual settings.

  • "OFF" : Deactivates automatic selection of element technology. No suggestions are issued, and no automatic resetting occurs.

eldegene

Element degenerated shape control. One of the following:

  • "ON" - If element shapes are degenerated, the degenerated shape function is employed and enhanced strain, simplified enhanced strain, and B-bar formulations are turned off (default).

  • "OFF" - If element shapes are degenerated, regular shape functions are still used, and the specified element technologies (e.g., enhanced strain, B-bar, uniform reduced integration) are still used.

Notes

The command default is mapdl.etcontrol('SUGGESTION', 'ON')

This command is valid for elements SHELL181, PLANE182, PLANE183, SOLID185, SOLID186, SOLID187, BEAM188, BEAM189, SHELL208, SHELL209, PLANE223, SOLID226, SOLID227, REINF264, SOLID272, SOLID273, SHELL281, SOLID285, PIPE288, PIPE289, ELBOW290.

Examples

Enable element tech control and degenerated shape control.

>>> mapdl.et(1, 'SOLID186')
>>> output = mapdl.etcontrol(eltech='SET', eldegene='ON')
>>> print(output)
ELEMENT TECHNOLOGY CONTROL PARAMETER FOR APPLICABLE ELEMENTS = SET.
 DEGENERATED ELEMENT SHAPE CONTROL PARAMETER FOR APPLICABLE ELEMENTS = ON.
