ansys.mapdl.core.Mapdl.emunit#
- Mapdl.emunit(lab='', value='', **kwargs)#
Specifies the system of units for magnetic field problems.
Mechanical APDL Command: EMUNIT
Command default:
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 8.85e-12 Farads/meter.
- Parameters:
- lab
str 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 forVALUE. 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
str User value of free-space permeability (defaults to 1) if
Lab= MUZRO, or free-space permittivity (defaults to 1) ifLab= EPZRO.
- lab
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. If the magnetic source field strength (H:sub:s ) 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.
