ElectricSymmetryValue
ElectricSymmetryValue[pred,vars,pars]
represents an electric symmetry boundary condition for PDEs with predicate pred indicating where it applies, with model variables vars and global parameters pars.
ElectricSymmetryValue[pred,vars,pars,lkey]
represents an electric symmetry boundary condition with local parameters specified in pars[lkey].
Details
- ElectricSymmetryValue specifies a symmetry boundary condition for ElectrostaticPDEComponent.
- ElectricSymmetryValue specifies a boundary condition for ElectrostaticPDEComponent and is used as part of the modeling equation:
- ElectricSymmetryValue is typically used to model a boundary with mirror symmetry along an axis.
- ElectricSymmetryValue models a boundary with mirror symmetry with dependent variable , independent variables and time variable .
- Stationary variables vars are vars={V[x1,…,xn],{x1,…,xn}}.
- The polarized form of ElectrostaticPDEComponent with vacuum permittivity in units of [], polarization vector in units of [] and volume charge density in units of [] is given by:
- ElectricSymmetryValue with boundary unit normal models:
- Model parameters pars as specified for ElectrostaticPDEComponent.
- ElectricSymmetryValue is effectively the same as ElectricFluxDensityValue with an electric flux of 0.
- The boundary predicate pred can be specified as in NeumannValue.
- If the ElectricSymmetryValue depends on parameters that are specified in the association pars as …,keypi…,pivi,…], the parameters are replaced with .
