Evening session (Gather Town): Discussion tables (19:30–21:00 GMT)

On Tuesday evening, we congregated in the Gather Town meeting room to have open discussions around a selection of topics.

Six tables each had a topic for discussion written on them. Everyone joined whichever table they want to, or moved between tables to drop into multiple discussions. The topics were:

Solvers, Time, Meshing + i/o, DG, HPC, Coupling to other software.
