Forces data collection

The force data collections are divided in 3 types, corresponding to specific force types:
  • Surface forces, obtained by nodal integration of dFmagS spatial quantity (surface magnetic force density). These forces can be computed only on surface supports that are situated at the interface between two regions with different magnetic permeability. For Steady state AC application, user has to specify the type of values to collect (continuous, instantaneous or pulsating).
  • Volume forces, obtained by local integration of dFLapV spatial quantity (volumic Laplace force density). These forces can only be computed on volume supports. For Steady state AC application, user has to specify the type of values to collect (continuous, instantaneous or pulsating).
  • Forces dedicated to rotating machines with mesh import, obtained by integration of magnetic pressure on a virtual cylinder in the air gap before applying them to the support nodes. These forces can only be computed on cylinder or circular supports.
    • The user should specify:
      • the virtual cylinder radius in the air gap on which magnetic pressure is integrated,
      • the length unit of the radius
    • The user can modify:
      • the number of integration points along the integration perimeter
      • the circle of local integration surrounding a node (enter 0 to force the optimal value computation)
No matters their type, the force data collections must be defined by:
  • A data support compatible with the chosen collection type
  • The step list for which the values need to be collected (complete scenario, specific interval or single step)
    Note: If the collection is defined before the project solving, the user has to specify the scenario for which he wants to collect data. The data will be collected during the solving with the defined scenario.
