capacitance

Post by Andy »

I use electrostatics for capacitance matrix calculation in 3D. There are body as ground and two small bodys inside big box as air.

You should set the BCs for the conductors using the "Capacitance Body = Integer i" keyword. The permutations are then carried automatically. If you define the Dirichlet BCs the hard way the system cannot perform the permutations and hence no capacitance matrix can be computed. See the Models Manual for more details.
