MAGOPT
MAGOPT, Value
Specifies options for a 3D magnetostatic field analysis.
ValueOption 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 byVALUE= 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 withVALUE= 3) or to multiply-connected iron domain problems (when preceded by a solution withVALUE= 1 and followed by a solution withVALUE= 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.
