ansys.mapdl.core.Mapdl.biot

Mapdl.biot(label='', **kwargs)

Calculates the Biot-Savart source magnetic field intensity.

Mechanical APDL Command: BIOT

Command default:

Calculate the H:sub:s field upon encountering the first solve command to produce a source field.

Parameters:

labelstr

Controls the Biot-Savart calculation:

• NEW - Calculate the magnetic source field intensity (H:sub:s ) from the selected set of source elements to the selected set of nodes. Overwrite any existing H:sub:s field values.

• SUM - Calculate the H:sub:s field from the selected set of source elements to the selected set of nodes. Accumulate with any existing H:sub:s field values.

Notes

Calculates the Biot-Savart source magnetic field intensity (H:sub:s ) at the selected nodes from the selected source elements. The calculation is done at the time the biot command is issued.

Source elements include primitives described by element SOURC36, and coupled-field elements SOLID5, LINK68, and SOLID98. Current conduction elements do not have a solved-for current distribution from which to calculate a source field until after the first substep. Inclusion of a current conduction element H:sub:s field will require a subsequent biot,SUM command (with SOURC36 elements unselected) and a solve command.

The units of H:sub:s are as specified by the current emunit command setting.

This command is also valid in PREP7.

Distributed-Memory Parallel (DMP) Restriction When used with SOLID5, LINK68, or SOLID98, the biot command is not supported in a DMP solution.
