ansys.mapdl.core.Mapdl.gmatrix#
- Mapdl.gmatrix(symfac='', condname='', numcond='', matrixname='', **kwargs)#
Performs electric field solutions and calculates the self and mutual conductance between multiple conductors.
Mechanical APDL Command: GMATRIX
- Parameters:
- symfac
str Geometric symmetry factor. Conductance values are scaled by this factor which represents the fraction of the total device modeled. Defaults to 1.
- condname
str Alphanumeric prefix identifier used in defining named conductor components.
- numcond
str Total number of components. If a ground is modeled, it is to be included as a component.
- matrixname
str Array name for computed conductance matrix. Defaults to GMATRIX.
- symfac
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.
