gauge

Mapdl.gauge(opt='', freq='', **kwargs)

Gauges the problem domain for a magnetic edge-element formulation.

APDL Command: GAUGE

Parameters
  • opt

    Type of gauging to be performed:

    ON - Perform tree gauging of the edge values (default).

    OFF - Gauging is off. (You must specify custom gauging via APDL specifications.)

    STAT - Gauging status (returns the current Opt and FREQ values)

  • freq

    The following options are valid when Opt = ON:

    0 - Generate tree-gauging information once, at the first load step. Gauging data is

    retained for subsequent load steps. (This behavior is the default.)

    1 - Repeat gauging for each load step. Rewrites the gauging information at each

    load step to accommodate changing boundary conditions on the AZ degree of freedom (for example, adding or deleting AZ constraints via the D or CE commands).

Notes

The GAUGE command controls the tree-gauging procedure required for electromagnetic analyses using an edge-based magnetic formulation (elements SOLID236 and SOLID237).

Gauging occurs at the solver level for each solution (SOLVE). It sets additional zero constraints on the edge-flux degrees of freedom AZ to produce a unique solution; the additional constraints are removed after solution.

Use the FREQ option to specify how the command generates gauging information for multiple load steps.

Access the gauging information via the _TGAUGE component of gauged nodes. The program creates and uses this component internally to remove and reapply the AZ constraints required by gauging. If FREQ = 0, the _TGAUGE component is created at the first load step and is used to reapply the tree gauge constraints at subsequent load steps. If FREQ = 1, the tree-gauging information and the _TGAUGE component are generated at every load step

If gauging is turned off (GAUGE,OFF), you must specify your own gauging at the APDL level.

This command is also valid in PREP7.
