Simulation of new generation gas detectors is rendered complicated due to the non-trivial nature of the electric field and simultaneous presence of several length-scales. Computation of the electrostatic field, however, is extremely important since streamers in gas volume and streamers across the dielectric surfaces are known to cause serious damage to Micro Pattern Gas Detectors (MPGD)and are the main factors in limiting their gain. In this paper, we present the use of a nearly exact Boundary Element Method (neBEM) solver that overcomes most of the limitations of FEM packages and is capable of producing accurate results.
