3D models

Altair Forum User

Good day,

I do not understand,  the question arises when you model a DI-ELECTRIC object in CADFEKO,  but when you view a cut in POSTFEKO, the object seems hollow inside (true even for PEC) - as seen in the diagram below.

1. Does this mean that the dielectric property is modeled as hollow?
2. How can the model be filled - with a dielectric medium for simulation?

Hello Farai,

The MoM and SEP are 'surface equivalence' solution methods. It is an advantage to not have to discretise the volume, since the surface results in less elements. Other solution methods such as FEM and FDTD require volume discretisation.
