Dear all,
I recently read the file of roe.mako in the installed directory
'PyFR-1.8.5\pyfr\solvers\euler\kernels\rsolvers', and met problems about
some functions and equations.
1. Is there any document listed the equations related to this roe solver?
I only found the equations related to Rusanov solver in appendix A of the
thesis of Dr. Witherden.
2. What is the role of '${pyfr.expand('inviscid_flux', 'ul', 'fl', 'pl',
'vl')};' in the roe.mako ? In my opinion, it is a function of
'inviscid_flux' and its input variables includes conserved quantity 'ul',
flux 'fl', pressure 'pl', and velocity 'vl'. With the command of
'pyfr.expand', the function of 'inviscid_flux' can be embedded within a
kernel.
Any hints are available.
Regards
Kiny
