HFSS基于頻率的邊界條件

2017-04-17 by:CAE仿真在線來源:互聯(lián)網(wǎng)

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
