323d4e3b31 Replaced all calls to AC_VTXBUF_IDX to acVertexBufferIdx etc in all files 2019-07-23 14:37:28 +03:00

074fb26df9 Added TODO_SINK comments. 
The comments were written to map out what essential part are needed for
resolving a system with graviating sink particles. No changes to the code
itself.

0bda016e17 Reviewed the Astaroth interface. Now there's a clear distinction between synchronous and asynchronous functions. For basic usage, we provide a set of functions that are always safe to call (acIntegrate, acLoad, etc), but because of this, must be quite restricted in the sense that f.ex. the whole mesh must be loaded at once and computations cannot be executed concurrently on multiple GPUs. For more advanced users we provide asynchronous functions (such as acLoadWithOffset). Since we cannot know how the asynchronous functions are called (for example, when the integration step has been fully completed and the halos of neighboring subgrids can be safely communicated between GPUs), the responsibility of synchronization must be left to the user. In the existing implementations we currently use only the basic "safe" set of functions (except in renderer.cc), so the existing functionality has not been changed with these latests commits. Autotests also pass. 2019-07-09 18:42:00 +03:00

eda2f6543b Created a new ForcingParams structure and some functions for generating and transferring the forcing parameters to the host/device 2019-07-08 15:43:37 +03:00

f9be905703 Corrected an unit coversion issue from forcing. 
Now noticing these because of switching to gcc 8.

609cfaea14 Commenting the unused variables in simulation.cc a few commits back was the wrong move since the variables are needed if LFORCING it set. 2019-07-03 17:46:50 +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.

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

9b2e9d376f helical_forcing_k_generator() added. 
Now Helical forcing almost works. I just need scale to force per tiome step
correctly. The current formulation is wrong.

Without randomization. Will add next.

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.
