JackHsu d1ca196ccd Added declaration of constants for sink particle. Still in the process of understanding how values are passed, but I've realized how physical equations are defined in stencil_process.sps and in principle I can replicate that for sink particle(which will mostly be gravity). 2019-07-29 13:18:24 +08:00
JackHsu 89e6f8673f Made corrections to some formatting issues. 2019-07-26 16:53:39 +08:00
JackHsu 9d625688ac Apparently my edit this time was unsuccessful, tons of error messeages showed up when I ran "make -j" command in working directory. However this commit is mainly for education purposes, it's so that Miikka (main) and others can see what I changed easily and can use as teaching reference. 2019-07-26 16:22:04 +08:00
jpekkila f74df5339f Cleaned up the include directory: removed all unnecessary stuff and moved common definitions to a separate file 2019-07-22 19:46:45 +03:00
jpekkila 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
jpekkila acc53e1c2b Merged master to acc_parameter_overhaul 2019-07-03 17:37:37 +03:00
jpekkila 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
Miikka Vaisala 98713ff9d2 A possible bug note added. Will look into late. 2019-07-03 14:49:10 +08:00
Miikka Vaisala 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.

Miikka Vaisala 4766441ffb Tryin to prepare autotest for forcing. 2019-07-02 18:24:41 +08:00
Miikka Vaisala 03689709df Merge branch 'master' into forcing 2019-07-02 16:43:10 +08:00
jpekkila 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
jpekkila 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
jpekkila 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
jpekkila 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
jpekkila d9be66f65f NOTE: Renamed LINDUCTION to LMAGNETIC throughout the project. 2019-07-01 13:40:24 +03:00
Miikka Vaisala 0600790f41 Corrected a bug in the timestep and some scaling problems. 
Now I can reach a saturated stated in forcing without crashing the code.

Miikka Vaisala 9f0be0d9ff Solved the forcing function boundary problem. 2019-07-01 11:06:42 +08:00
Miikka Vaisala f04ef8e64c Forcing function issue not yet fully resolved. 
Now brain hurs. No more today. Break needed.

Miikka Vaisala 94a25383a9 Trying to calculate the forcing scaling. 
Causes nans very quickly. Will need to look closer tomorrow again.

jpekkila ffe9df1bb0 LFORCING was turned off in stencil_process and the autotests failed, re-enabled 2019-06-26 14:08:56 +03:00
Miikka Vaisala 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.

Miikka Vaisala 231a8aa06e Trying to figure out how to upload values to GPU. 2019-06-26 15:23:46 +08:00
Miikka Vaisala 5cacda2850 Helical forcing funtion works. 
But we will need a wavenumber generator to add stochasticity.
 2019-06-26 13:15:28 +08:00

Not the idead form. Not yet tested.
