- Mapdl.dflx(node='', bx='', by='', bz='', bx2='', by2='', bz2='', **kwargs)#
Imposes a uniform magnetic flux B on an edge-element electromagnetic model.
Mechanical APDL Command: DFLX
- Parameters:
- node
str Nodes at which the edge-flux (AZ) constraints corresponding to the uniform magnetic flux are to be specified. Valid options are ALL (default) or Component Name. If ALL, constraints are applied to all selected nodes ( nsel ).
- bx
str Real components of magnetic flux B.
- by
str Real components of magnetic flux B.
- bz
str Real components of magnetic flux B.
- bx2
str Imaginary components of magnetic flux B.
- by2
str Imaginary components of magnetic flux B.
- bz2
str Imaginary components of magnetic flux B.
- node
Notes
The dflx command sets the constraints on the edge-flux (AZ) degrees of freedom to produce a uniform magnetic flux B in an edge-based electromagnetic analysis using one of these element types:
SOLID226,SOLID227,SOLID236, orSOLID237. The command ignores the corner nodes of the elements (even if they were selected) and imposes the AZ-constraints on the mid-side nodes only. The AZ-constraints are imposed in the active Cartesian coordinate system. A non-Cartesian coordinate system will be ignored by the dflx command.The edge-flux constraints at the mid-side nodes are derived from the magnetic vector potential A, which is related to the imposed magnetic flux B as follows:
\[equation not available\]where r is the position of the mid-side node.
The dflx command creates a component named _DFLX for the constrained midside nodes. You can use this component to delete the constraints imposed by the dflx command.
This command is also valid in PREP7.
