Flexi Liska Wendroff Implosion
This movie shows a FLEXI calculation of the Liska-Wendroff implosion problem.
FLEXI is a high performance open source computational fluid dynamics (CFD) code.
In this benchmark simulation, a shock wave originates in the lower left hand corner, and bounces around inside the domain, reflecting off the walls. Jets are produced as a result of these reflections. These jets collide at the origin, forming a narrow jet that “squirts out” along the y=x axis. The reflecting shock waves continually interact with this jet of dense gas over time as the calculation proceeds.
