q1 = +10-6 C/m
q2 = -10-6 C/m Analysis Assumptions and Modeling Notes
Two dimensional quad elements of PLANE121 are used out to the radius of 470 mm. At this radius the INFIN110
(quad elements) with length equal to two times the 470 mm are used. Due to symmetry only one quadrant

(positive X and positive Y), containing one half of each of two wires (carrying half of positive and negative charge
magnitude), is modeled with flux-normal boundary conditions at X = 0.0 and Y = 0.0 axes. Note, since 4-node
INFIN110 elements are used with 8-node PLANE121, the infinite element domain is required to mesh before the
finite element domain to drop off automatically the midside nodes from the PLANE121 element faces at the interface of the finite and infinite element domain. SF command with label, INF is used to flag the exterior surface
(at infinity) of the INFIN110 elements. The charge is applied as a point load at the center of each of two w...
