KAPPA - Karlsruhe parallel program for aerodynamics

Research in fluid dynamics can be done on both an experimental and numerical basis, For the latter a computer code needs to be written in order to solve the governing fluid flow equations. The KAPPA code is a CFD simulation package serving as a platform to develop faster and more accurate numerical schemes, better physical models, or as an engineering tool for the simulations of flows in technical equipment. Another important subject is the training and education of students or engineers. Since CFD is highly calculation intensive, new computer architectures such as vector and parallel computers are necessary to treat more complex flow fields or to resolve these flows more accurately. Therefore KAPPA has been specially designed to be used on these architectures. The structure of the code is such that the solution of additional transport equations needed for the simulation of chemistry, turbulence modeling, multiphase flows etc. can be easily implemented. In order to treat complex geometries the code is block structured. The finite volume method is used to discretize the equations in space. The code is written in Fortran 90 using the highly desirable new feature of this language. For the application of the code on parallel computers a message passing tool has been used.
