In this model, the packing behavior of grains is simulated using three force models: Hertz-MD, Hertz-MD with adhesion, Hertz-MD with adhesion and van der Waals forces. The packing efficiency is calculated to quantify the extent of packing observed. En savoir plus
In this model, we use the Bioheat Transfer interface to solve the Pennes bioheat transfer equation. The problem is in 1D and formulated to be dimensionless. The results are compared against analytical solutions derived in a journal paper (Ref. 1). A mesh convergence study shows that the ... En savoir plus
This model simulates the initiation of streamers from suspended metal particles, their propagation under a high electric field, and their subsequent merging. The discharge current flows into the metal particles, which are maintained at equal potential. These suspended particles enhance ... En savoir plus
In this model, the transmitter (microstrip patch) and receiver (Yagi–Uda) antennas are modeled simultaneously in the FEM domain and are coupled with FEM–BEM coupling. The results are compared with the analytical Friis transmission formula. In detail, the emw and emw2 interfaces find out ... En savoir plus
This example illustrates a linear buckling analysis conducted for a corrugated conical shell, utilizing a single sector of the geometry along with cyclic symmetry periodicity edge conditions. The results are compared to those using the full shell geometry. En savoir plus
A waveguide filter is designed using shape optimization by moving and scaling rectangles in the geometry. The irises of the initial geometry are optimized to ensure good bandpass response and out-of-band rejection, while maintaining the double mirror symmetry. The EGO optimization solver ...
