也不知道Plane233究竟支持不支持速度效应,其手册资料里面是自相矛盾的!
不支持
Whenever possible, ANSYS, Inc. recommends using PLANE233 (the current-technology electromagnetic element) rather than PLANE13 or PLANE53 (legacy magnetic elements). See Legacy vs. Current-Technology 2-D Magnetic Elements (p. 19) for a list of the capabilities that are only available with PLANE233. PLANE233 does not support nonlinear harmonic analysis, velocity effects, or LMATRIX calculations.
支持
PLANE233 is applicable to 2-D static, time-harmonic and time-transient electromagnetic analyses. The magnetic analysis option is typically used to model air, iron, nonferrous materials and permanent magnets. The analysis is driven by the current density applied as an element body load. The electromagnetic analysis option is suitable for modeling solid (massive) conductors. This analysis may be voltageor current-driven, or circuit-fed. The electromagnetic analysis has the option to suppress the eddy current effect in time-varying analyses to model stranded conductors. The velocity effects can be taken into account in a static, time-harmonic or time-transient electromagnetic analysis.
但是,在电磁场指南中的一个实例(实心转子电机),用的单元是Plane233,由此看来,这个单元是支持速度效应的,虽然速度效应并无多大用处,仅适用于诸如实心转子电机和涡流制动器这样的一些特殊场合。 |
