APDL Command: EMUNIT

Specifies the system of units for magnetic field problems.

Parameters
lab

Label specifying the type of units:

MKS - Rationalized MKS system of units (meters, amperes,

henries, webers, etc.). Free-space permeability is set to 4 πe-7 henries/meter. Free- space permittivity is set to 8.85 e-12 F/m.

MUZRO - User defined system of units. Free-space

permeability is set to the value input for VALUE. Other units must correspond to the permeability units. Relative permeability may be altered to absolute values.

EPZRO - User defined system of units. Free-space

permittivity is set to the value input for VALUE. Other units must correspond to the permittivity units.

value

User value of free-space permeability (defaults to 1) if Lab = MUZRO, or free-space permittivity (defaults to 1) if Lab = EPZRO.

Notes

Specifies the system of units to be used for electric and magnetic field problems. The free-space permeability and permittivity values may be set as desired. These values are used with the relative property values [MP] to establish absolute property values.

Note:: : If the magnetic source field strength (Hs) has already been calculated [BIOT], switching EMUNIT will not change the values.

For micro-electromechanical systems (MEMS), where dimensions are on the order of microns, see the conversion factors in System of Units in the Coupled-Field Analysis Guide.

This command is also valid in SOLUTION.
