CFDLab descriptions CFDLab is an easy-to-use educational & engineering tool for 2D computational fluid dynamics . It solves in-/external potential incl. anisotropic Poisson diffusion & convection-diffusion problems for single bounded domains. Data input processing & data output are organised by a project manager co-operating with linked interactive & interdependent database & graphics components. The five tabs of the main interface highlight the problem-solving steps: input nodes input parameters process output potentials & finally output fluxes . Numerous example projects are included with documentation & source codes for computing boundary values & benchmarks that allow users to compare the effects of varying boundary conditions values scale factors approximating functions & different types of governing equations. Data input is realised by working interactively in graphics displays & database grids that keep each other automatically updated when data is changed. Several wizards e. g. for rectangular & elliptic boundaries allow to input data by a few mouse clicks. Data output can be viewed by using either ASCII files database grids or 3D surface plots for potentials & 2D vector plots for fluxes. Plots can be adjusted as wanted & watched as animations in movie style for time-dependent problems. Shareware registration
