Sažetak
We present a new, very efficient and robust method for solving electrostatic problems. The basic idea of the method is rather simple, but has not been exploited till now. The essence of the method is achieving of the equipotentiality of the conducting surfaces by the iterative nonlocal charge transfer. The testing of the method in syste ms allowing analytical solutions shows excellent agreement. Besides the simple physical idea, the computational behavior of the method is very appealing. It scales linearly in memory with the number of elements and it converges geometrically without the occurrence of critical slowing down. The presented method can be extended in application to other types of problems, electrostatics being very specific example in which one can remain only on the boundaries of the objects involved in the calculation. Due to high efficiency and low resource demands, this method could prove to be very useful in many areas that require electrostatic calculations of high precision and detail - medical applications, detector construction, printed electronics being just some of them.
