When a gap element is specified, electrical potentials are defined on both sides of it. If you define a SUFCUR surface to overlap that surface, a positive potential is defined on the positive side of the gap (in the right-hand thread direction of the element) and the negative side is set to zero. <\/p>\n
Suppose we have a closed loop conductor as shown in Fig. 1. In this case we can use the symmetry condition, but we will solve for the entire upper half. Define a gap surface as shown in the figure. Gap surface elements can also be used as SUFCUR definition elements. First, create a mesh by extending in the z-direction from pre_geom2D.neu and 2D_to_3D, define the gap surface and SUFCUR surface with input, and perform an AC steady-state analysis. The loop current is induced as shown in Fig. 1, and the heat generation distribution is shown in Fig. 2. <\/p>\n
Here we have shown the case where SUFCUR is defined on a symmetrical surface, but it can also be defined in an asymmetrical position. It can also be used in combination with a gap element on one end face, even when using rotational symmetry. $\\Rightarrow$ "SUFCUR at asymmetric locations or periodic boundaries"<\/font><\/a>. <\/p>\n <\/p>\n Set the gap surface and SUFCUR definition surface to serve as a dual-use surface. <\/p>\nHow to use<\/h3>\n
