openCFS-Data: Data Pre-Post-Processing Tool for openCFS

Abstract: Many numerical simulation tools have been developed and are on the market, but there is still a strong need for appropriate tools capable to simulate multi-field problems, especially in aeroacoustics. Therefore, openCFS provides an open-source framework for implementing partial differential equations using the finite element method. Since 2000, the software has been developed continuously. The result of is openCFS (before 2020 known as CFS++ Coupled Field Simulations written in C++). In this paper, we present for the first time the CFS-Data, the open-source pre-post-processing part of openCFS with a focus on the aeroacoustic source computation (called filters).
