求助:约束方程怎么实现啊!
请问高手们,我想分析转子在不同位置时的磁路,要想在分析中移动转子,我知道要有个约束方程,这个约束方程的设定需要哪些条件啊!比如单元或节点什么的,再组成组件,具体的我不知道,请你们帮帮我啊!加约束方程
命名格式：CE, NEQN, CONST, NODE1, Lab1, C1, NODE2, Lab2, C2, NODE3, Lab3, C3
NEQN
Set equation reference number:
n—Arbitrary set number.
HIGH—The highest defined constraint equation number. This option is especially useful when adding nodes to an existing set.
NEXT—The highest defined constraint equation number plus one. This option automatically numbers coupled sets so that existing sets are not modified.
The default value is HIGH.
CONST
Constant term of equation.
NODE1
Node for first term of equation. If -NODE1, this term is deleted from the equation.
Lab1
Degree of freedom label for first term of equation. Structural labels: UX, UY, or UZ (displacements); ROTX, ROTY, or ROTZ (rotations, in radians). Thermal labels: TEMP, TBOT, TE2, TE3, . . ., TTOP (temperature). Electric labels: VOLT (voltage). Magnetic labels: MAG (scalar magnetic potential); AX, AY, or AZ (vector magnetic potentials).
C1
Coefficient for first node term of equation. If zero, this term is ignored.
NODE2, Lab2, C2
Node, label, and coefficient for second term.
NODE3, Lab3, C3
Node, label, and coefficient for third term.
