ParameterSymbolDescriptionDimension (Range)
1. NameN/AUse to set the name of the Magnetic entity.N/A
2. GroupN/AUse to select a group. All bodies of each group should be fixed to each other.N/A
3. Coordinate SystemN/AUse to set a reference frame to generalize the forces. The default is set to the marker which is located on the mass center of the group. This marker belongs to 1st body of the group.N/A
4. Project PathN/A

Shows the project file path for Maxwell.

Note that this field and the Design Name field (below) are automatically populated after clicking Generate Maxwell Project.

N/A
5. Design NameN/ASet a design name for the Maxwell project. The design settings depend on how you have set up the Maxwell model. If you are opening the Maxwell project directly, designs are listed and you can select from these. If you are generating the Maxwell project from Motion, this should be input manually.

Auto Stop

The Auto Stop tab allows you to configure the conditions under which the solver will automatically stop the solution. This can be based on measurement of Position or Force, as described below.

  • Position

    If the condition below is met 3 times, the solver will be terminated. The variation of all body positions should be satisfied.

    Max – Min < Criterion

    Inflection points are defined as Max (+ → -) and Min (- → +), as shown in the figure below.

    Example of Auto Stop by position measurement

  • Force

    The variation of all interface forces from Maxwell should satisfy this condition 3 times in succession:

    Fcurrent – Fprevious < Criterion
