Finally, we have a plot of the far-field spectrum of our PCA obtained by combining theFar-Field Calculationnode with theTime to Frequency FFTstudy. We find that the pulse has the strongest peak at approximately 0.75 THz but with significant power all the way up to nearly 5 THz. Additionall...
For the purpose of understanding total and partial inductances, let’s start by considering a model of a square loop of wire, as shown in the figure below. When current flows along this closed loop there will be a magnetic field in the surrounding space. We can define and compute the tot...
Here, we have two types of materials, a fluid (water) and a linear elastic material (aluminum), and we want to run a frequency-domain analysis to get the steady-state time-harmonic solution of the total acoustic field. To set up the model, we choose theAcoustic-Solid Interaction, F...
An interesting consequence of this approach is that the boundaries of the modeling domain no longer need to provide a current return path. This opens up the possibility for alternative boundary conditions on the exterior of the modeling domain, which can be used to model an insulative surrounding ...
