Acoustic Pulse
I want to validate a Euler equations solver using the acoustic pulse as test case.
However, the exact solution of it, is complex to derived due to the appearence of integral which involves a bessel function. What can i do for derive the exact solution? Any suggestions? |
would it have to be an acoustic pulse? you may start with sth simpler and build up from there to validate the code...e.g. the standard test case: pulse in rho..
|
Could you tell me more information for this case? Some papers which setup the test?
The convection of isentropic vortex is not good problem for validation? |

Start by using a density pulse with a velocity field (should be convected along the streamlines).
If that works, use the method of the manufactured solution to create sth like a sinewave solution and test convergence with that - if you actually have access to the code and can add a source term, that is.... |
wolfram alpha
just ask wolframalpha.com to integrate it for you.
