Detailed description#

Defines an equipotential-surface electric-field source by assigning potentials to nodes.

POTNODE#

POTNODE(17.11)#
Text-format section
Fixed parameter set 1#
[row, col] = [1, 1]
Type=S

Specifies the equipotential-surface electric-field source POTNODE.

SERIES_ID#

SERIES_ID(17.11)#
Text-format section
Fixed parameter set 1#
[row, col] = [1, 2]
Type:

Integer (I)

Description:

Source-term identifier.

SURFACE_MAT_ID#

SURFACE_MAT_ID(17.11)#
Text-format section
Fixed parameter set 1#
[row, col] = [1, 3]
Type=I

Optional property ID of the surface elements containing the nodes to which potentials are assigned. 0 is also allowed. When the value is > 0, nodes are searched preferentially among the surface elements, reducing the search time.

TIME_ID#

TIME_ID(17.11)#
Text-format section
Fixed parameter set 1#
[row, col] = [1, 5]
Type=I

Data ID specifying the time variation TIME_ID(18).

Specifies the time variation of charge (current) or potential according to POT_OR_CHARGE.

NODE_IDS#

NODE_IDS(17.11)#
Text-format section
Fixed parameter set 1#
[row, col] = [2, 1]
Type=I(0,1)

Identifiers of the nodes to which potentials are assigned.

POTENTIALS#

POTENTIALS(17.11)#
Text-format section
Fixed parameter set 1#
[row, col] = [2, 2]
Type=E

Normalized potential (V). The node potential is the value obtained by multiplying this potential by the time variation specified by TIME_ID(18).
