MAGOPT

MAGOPT, Value
Specifies options for a 3D magnetostatic field analysis.

Valid Products: Pro | Premium | Enterprise | PrepPost | Solver | AS add-on

Value

Option key:

0

 — 

Calculate a complete H field solution in the entire domain using a single (reduced) potential.


Caution:  When used in problems with both current sources and iron regions, errors may result due to numerical cancellation.


1

 — 

Calculate and store a preliminary H field in "iron" regions (μr ≠ 1). Requires flux-parallel boundary conditions to be specified on exterior iron boundaries. Used in conjunction with subsequent solutions with VALUE = 2 followed by VALUE = 3. Applicable to multiply-connected iron domain problems.

2

 — 

Calculate and store a preliminary H field in "air" regions (μr = 1). The air-iron interface is appropriately treated internally by the program. Used in conjunction with a subsequent solution with VALUE = 3. Applicable to singly-connected iron domain problems (with subsequent solution with VALUE = 3) or to multiply-connected iron domain problems (when preceded by a solution with VALUE = 1 and followed by a solution with VALUE = 3).

3

 — 

Use the previously stored H field solution(s) and calculate the complete H field.

Notes

Specifies the solution sequence options for a 3D magnetostatic field analysis using a scalar potential (MAG). The solution sequence is determined by the nature of the problem.

You cannot use constraint equations with Value = 1.

This command is also valid in PREP7.

Distributed-Memory Parallel (DMP) Restriction  —  MAGOPT,3 is not supported in a DMP solution when the following contact elements are present in the model: CONTA174, CONTA175, or CONTA177.
