Card 9 - XCAP Capacitances
This optional card specifies the parameters and options for defining capacitances for elements.
Parameters: KODE, N1, T1, T2, T3
KODE
KODE is the code XCAP (or 2)
N1
N1 is an element number, or a group name.
T1
T1 is an element number or 0. T1 = 0 defaults to T1 = N1. If N1 is a group name, T1 must be 0.
T2
T2 is the capacitance value of the elements N1 through T1 or of group N1.
T3
T3 may be:
T3 = AREA(or 1.E36): The capacitance generated will be equal toT2 * areaof the element.T3 = LENGTH(or 4.E36): The capacitance generated will be equal toT2 * lengthof the beam element.T3 = VOLUME(or 3.E36): The capacitance generated will be equal toT2 * volumeof the element.- Blank: The capacitance is specified directly by
T2.
Code example
XCAP 3 5 3
$ ELEMENTS 3,4, AND 5 HAVE CAPACITANCES OF 3.0
Notes
This card specifies capacitances for elements N1 through T1. Alternatively, capacitances may be calculated from geometry by specifying non-zero specific heats and densities on MAT Cards for Card 5a elements.
Capacitances calculated from geometry are summed with those specified on XCAP Cards by the MEREL module.
