搜索HFSS基于頻率的邊界條件

在基于頻率的邊界條件中,可以利用系統(tǒng)變量:Freq
這個變量,讓你可以取得求解的準(zhǔn)確頻率值(快速掃頻除外)。
Frequency-Dependent Boundaries and Excitations
In general, boundary and excitation parameters cannot depend on intrinsic functions. An exception is when a parameter depends on the variable Freq, which represents the solution frequency. The following boundary:parameters can be assigned an expression that includes Freq:
- Impedance boundary: - the Resistance and Reactance parameters.
- Finite conductivity :boundary - the Conductivity parameter. If a material is specified, the mate-rial can be frequency dependent.
- Slave boundary :- the Phase parameter.
- Lumped RLC boundary :- Resistance, Inductance, and Capacitance parameters.
- Layered impedance boundary :- materials assigned on layers can be frequency dependent.
-
Anisotropic
Impedance boundary :- Resistance and Reactance parameters.,
Note
Dependence on Freq is supported for single-frequency solutions and for Discrete and Interpolating frequency sweeps. If a Fast sweep is requested, the solution will be valid for the center frequency, but may not be valid at other frequencies.
其實在hfss內(nèi)部還有許多變量可以利用,hfss叫做
Intrinsic Variables 即內(nèi)部變量或系統(tǒng)變量
以上這些變量都可以加以利用
