`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 (μ

_{r}≠ 1). Requires flux-parallel boundary conditions to be specified on exterior iron boundaries. Used in conjunction with subsequent solutions with= 2 followed by`VALUE`

= 3. Applicable to multiply-connected iron domain problems.`VALUE`

**2**—

Calculate and store a preliminary H field in "air" regions (μ

_{r}= 1). The air-iron interface is appropriately treated internally by the program. Used in conjunction with a subsequent solution with= 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).`VALUE`

**3**—

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

Specifies the solution sequence options for a 3-D 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.
