Aim of project
The ADIGMA project will concentrate on technologies showing the highest potential for efficient higher-order discretizations. The main scientifi c objectives of the ambitious ADIGMA project are summarized as follows:

Further development and improvement of key ingredients for higher-order space discretization methods for compressible Euler, Navier-Stokes and RANS equations;

Development of higher order space-time discretizations for unsteady flows;

Development of novel solution strategies to improve efficiency and robustness of higher-order methods enabling largescale aerodynamic applications;

Development of reliable adaptation strategies including error estimation, goal-oriented isotropic and anisotropic mesh refinement;

Utilization of innovative concepts in higher-order approximations and adaptation strategies for industrial applications;

Critical assessment of newly developed adaptive higher-order methods for industrial aerodynamic applications.

Expected results

Development of the parallelization algorithms used in CFD, which are based on the domain decomposition principle (the problem of load balancing between processors), parallelization of linear and nonlinear problems, parallelization of timedependent simulations and the estimation of performance on computers of different architecture (homo and heterogeneous clusters);

Development of anisotropic mesh adaptation and their coupling with selected methods for simulation of fl uid fl ow (esp. the problem of evaluation of the tensorial error estimator, extension to 3D flows and/or time dependent flows, application to simulation of shock-waves, boundary layers as well as tip vortices).
