A compact ring imaging Cherenkov detector is being developed to meet the requirements for charged particle identification for the PANDA experiment at the FAIR (Facility for Antiproton and Ion Research) project. It will cover the barrel region (large range of solid angle and momentum) of the PANDA multi-purpose detector, which will study the nature of strong interactions in detail. The concept and the current design of the PANDA Barrel DIRC were inspired by the successful BABAR DIRC with some important improvements, such as fast photon timing, a compact expansion volume, and focusing optics. Simulation of the detector within Geant4 is an essential acpect of the R&D of the PANDA Barrel DIRC, which focuses on cost optimization and performance improvement. Several design options were implemented in the simulation, and a fast reconstruction procedure based on look-up tables was used to determine the photon yield per particle and the single photon Cherenkov angle resolution. We present the detatils of comparison of these designs.
