CFDLab is an easy-to-use educational and engineering tool for 2D computational fluid dynamics (CFD). It solves in-/external potential (Laplace) incl. anisotropic, Poisson, diffusion, and convection-diffusion problems for single bounded domains. Data input, processing and data output are organised by a project manager co-operating with linked interactive and interdependent database and graphics components.


The five tabs of the main interface highlight the problem-solving steps: input nodes, input parameters, process, output potentials (viewed in 3D graphs), and finally output fluxes (as 2D vector plots). Numerous example projects are included, with documentation and source
codes for computing boundary values and benchmarks that allow users to compare the effects of varying boundary conditions, values, scale factors, approximating functions, and different types of governing equations.

Data input is realised by working interactively in graphics displays and database grids that keep each other automatically updated when data is changed. Several wizards, e.g. for rectangular and 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 and 2D vector plots for fluxes. Plots can be adjusted as wanted and watched as animations in movie style for time-dependent problems.
