Validation Data for Riemann vacuum solver

Flexflix · August 2, 2018, 11:22

Hello everyone

I wrote a riemann solver on c++ for my term paper and i'm searching for validation data for my vacuum cases. Does someone know a source where i can find another calculation of a riemann vacuum case, which i can compare with mine?

I already searched on google for "riemann solver vacuum test case", but coudn't find something usefull

For non vacuum cases i use the ToroExact solver from git as validation

My thanks in advance ^^

Not an expert here but, are we talking about near-vacuum or exact vacuum?

My Solver should work for exact vacuum and the exact calculation is what i want to validate

I programmed the solver from the book "Riemann Solvers and Numerical Methods for Fluid Dynamics" from Eleuterio F. Toro on page 115 to page 157
