Only the magnetic vector potential (MVP) formulation (see 2D Static Magnetic Analysis) is valid in eddy current regions for transient magnetic analysis. Therefore, you can use only the following element types to model eddy current domains.
Table 4.1: 2D Solid Elements
| Element | Dimens. | Shape or Characteristic | DOFs | Notes |
|---|---|---|---|---|
| PLANE13 | 2D | 4-node quadrilateral or 3-node triangular | Up to four at each node; these can be magnetic vector potential (AZ), displacements, temperature, or time-integrated electric potential | Supported for cyclic symmetry (periodic) analysis, static only. |
| PLANE233 | 2D | 8-node quadrilateral or 6-node triangular | Up to three at each node; these can be magnetic vector potential (AZ), electric potential/voltage drop or time-integrated electric potential/voltage drop (VOLT), electromotive force or time-integrated electromotive force (EMF) |
Current-technology element [1]Supported for cyclic symmetry (periodic) analysis. |
Whenever possible, Ansys, Inc. recommends using PLANE233 (the current-technology electromagnetic element) rather than PLANE13 (legacy magnetic element). See Older vs. Current 2D Magnetic Element Technologies for a list of the capabilities that are only available with PLANE233.
Some procedural steps discussed here do not apply applicable to PLANE233. For information on the differences between PLANE233 and PLANE13, see Older vs. Current 2D Magnetic Element Technologies.
