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)
