78aba6428e Updated the copyright years throughout the project 2019-07-16 14:28:32 +03:00

7abb959828 Overhaul to the user-defined parameters done: All logical switches, parameters and vertex buffer handles are now defined in a single header file (the default location is acc/mhd_solver/stencil_defines.h). This header is used when preprocessing the DSL sources and is linked to the include/ directory when calling scripts/compile_acc.sh. astaroth.h is now used for configuring internal stuff only and should not be modified by users 2019-07-03 19:01:16 +03:00

81a09501b8 Removed deprecated LNT0 and LNRHO0 defines, now the actual configuration parameters are used (AC_lnrho0 and AC_lnT0). Also accidental autoformatting again, there seems to be stray spaces before linebreaks in some files which get automatically removed by my text editor 2019-07-03 17:23:37 +03:00

334ff868d9 Forcing disabled from autotest and from defaults. 
It is not suitable function of the autotest tool. If there in really a
mandatory need to add it. I will need special help from Johannes.

d9b07a59b5 Tested with hydro, hydro + magnetic, hydro + magnetic + entropy and hydro + magnetic + entropy + forcing. Autotests passed in all cases. 2019-07-01 19:01:42 +03:00

1e6740f999 Added the equations for hydro only for both CPU and GPU. NOTE: NOT RIGOROUSLY CHECKED FOR CORRECTNESS. I just took the equations used with entropy and removed the terms which included entropy and magnetic fields 2019-07-01 18:56:13 +03:00

21e9fc943b Removed all defines from the stencil assembly and processing files and moved them to the new stencil_defines header. There were spaces after some linebreaks which were removed when I autoformatted the code and that's why there seems to be more changes that there actually is. 2019-07-01 18:40:13 +03:00

b8869bb848 Linked the defines used by the DSL and astaroth.h. Now f.ex. LENTROPY has to be set only once in acc/mhd_solver/stencil_defines.h and it is propagated throughout the whole project. The name for stencil_defines.h is not final and may change if I come up with a better name. In any case, there is now a standard header associated with each DSL solver where the user can set defines, and declare arrays (VTXBUF_LNRHO) and device constants (uniforms). 2019-07-01 18:37:56 +03:00

0600790f41 Corrected a bug in the timestep and some scaling problems. 
Now I can reach a saturated stated in forcing without crashing the code.

f04ef8e64c Forcing function issue not yet fully resolved. 
Now brain hurs. No more today. Break needed.

Causes nans very quickly. Will need to look closer tomorrow again.

be0e46c814 Can move forcing vector information now from the host to device. 
next step in to generate random waves in the CPU with a chosen degree of helicity etc.

5cacda2850 Helical forcing funtion works. 
But we will need a wavenumber generator to add stochasticity.
