gmatrix

Mapdl.gmatrix(symfac='', condname='', numcond='', matrixname='', **kwargs)

Performs electric field solutions and calculates the self and mutual

APDL Command: GMATRIX conductance between multiple conductors.

Parameters
symfac

Geometric symmetry factor. Conductance values are scaled by this factor which represents the fraction of the total device modeled. Defaults to 1.

condname

Alphanumeric prefix identifier used in defining named conductor components.

numcond

Total number of components. If a ground is modeled, it is to be included as a component.

matrixname

Array name for computed conductance matrix. Defaults to GMATRIX.

Notes

To invoke the GMATRIX macro, the exterior nodes of each conductor must be grouped into individual components using the CM command. Each set of independent components is assigned a component name with a common prefix followed by the conductor number. A conductor system with a ground must also include the ground nodes as a component. The ground component is numbered last in the component name sequence.

A ground conductance matrix relates current to a voltage vector. A ground matrix cannot be applied to a circuit modeler. The lumped conductance matrix is a combination of lumped “arrangements” of voltage differences between conductors. Use the lumped conductance terms in a circuit modeler to represent conductances between conductors.

Enclose all name-strings in single quotes in the GMATRIX command line.

GMATRIX works with the following elements:

SOLID5 (KEYOPT(1) = 9)

SOLID98 (KEYOPT(1) = 9)
