L1d: Lagrangian Quasi-1D flow simulation
Space-time diagram of wave processes in the X2 expansion tube for a Mach 10, high total-pressure operating condition. Simulation and figure preparation by David Gildfind, 2012.
What does L1d do?
l1d is our specialist simulation code for quasi-one-dimensional gas dynamics.
It is usually applied to the simulation of entire shock-tube or expansion-tube facilities
and has a role to play in the design of new experimental machines.
