About This Product
Features
■ No spatial mesh required (high-precision spatial electric field)
The finite element method treats potential as a variable. Therefore, elements are required not only for objects such as electrodes and dielectrics, but also for the entire spatial region of the analysis target. In contrast, ELFIN treats sources such as electric charge as a variable. Therefore, analysis can be performed using elements only for objects where sources exist. Since there are no sources in space, elements are not required.
■ No boundary conditions required
In ELFIN, the analysis domain extends to infinity. Therefore, there is no need to specify boundary conditions.
■ Calculation of potential and electric field using analytical formulas
In ELFIN, element integration is performed using analytical formulas on the element surface rather than numerical integration over multiple points. This allows for highly accurate calculations even near the surface.
■ High-precision spatial electric field
In the finite element method, spatial electric field calculations are calculated from the potential of the spatial mesh, which reduces accuracy. However, ELFIN calculates the electric field directly from the source, so accuracy is not compromised. The electric field generated by the source is calculated using analytical integral formulas. Therefore, the electric field is highly accurate even near the element.
■High-Precision Force and Torque
Maxwell stresses are calculated from highly accurate spatial electric fields, resulting in high accuracy.
■High-Precision Even with Coarse Element Meshing
The electric field rapidly decreases outside an object. As a result, the potential changes in a complex manner outside an object. The potential used in the finite element method changes significantly outside an object. Therefore, spatial regions require a finer meshing than the object's interior. Furthermore, since 3D electric fields propagate in three directions, they change more rapidly than 2D electric fields, so 3D analysis requires a finer meshing than 2D analysis.
On the other hand, sources used in ELFIN exist only inside or on the surface of an object, not outside it. Even in locations where the potential changes in a complex manner, if there are no sources there, the elements themselves are unnecessary.
Furthermore, source changes are gradual within and on the surface of objects where elements are required. Therefore, ELFIN generally does not require as fine a meshing as finite element methods.
