A Gas Dynamics Toolkit in D

The Eilmer flow simulation code is the main simulation program in our collection of gas dynamics simulation tools . An example of its application is shown here with the simulation of the hypersonic flow over the BoLT-II research vehicle that is to be flown in 2022. BoLT-II simulation with steady-state variant of the Eilmer code. Flow is from bottom-left to top-right of the picture. Only one quarter of the vehicle surface, coloured grey, is shown. Several slices through the flow domain are coloured with the
