d4ee066b3c Periodic boundary conditions work with switchable system. 
Still some issue with the custom alternatives. Need to look into kernels again.

830b8ad179 Disabled LBFIELD by default as there are no autotests for it 2020-09-14 13:27:09 +03:00

b815b62aa7 Enhanced simulation cc. Now magnetic fields diagnostics invoked if needed. 
Also more exit condition so that the simulation will terminate if nan happens or timestep becomes too short.

450526b8e1 B-field calculation to the DSL file. 
Still needs corresponding things elsewhere...

7848dedfbe Gauge correction to the induction equation for the sake of numerical stability. 
Used in my dynamo work, but apparantly was not done to the main repo.

0ccd4e3dbc Major improvement: uniforms can now be set to default values. The syntax is the same as for setting any other values, f.ex. 'uniform Scalar a = 1; uniform Scalar b = 0.5 * a;'. Undefined uniforms are still allowed, but in this case the user should load a proper value into it during runtime. Default uniform values can be overwritten by calling any of the uniform loader funcions (like acDeviceLoadScalarUniform). Improved also error checking. Now there are explicit warnings if the user tries to load an invalid value into a device constant. 2020-01-28 18:17:31 +02:00

ff12332f06 Clarified the syntax for real number literals. 1.0 is the same precision as AcReal, 1.0f is an explicit float and 1.0d is an explicit double. 2019-10-07 18:24:32 +03:00

8c1e603a98 On second thought, let's revert the changes in mhd_solver and use the file I already modified instead of doing the same changes twice 2019-10-07 17:29:53 +03:00

b4cd92da0c Now compiles and runs. 
PLEASE NOTE THAT FLAGS NEED TO BE SET SEPARATELY IN simulation.cc and renderer.cc FOR LSINK and LFORCING!

20138263f4 The previous attempt (dsl_feature_completeness_2019-08-23) to enable arbitrary kernel functions was a failure: we get significant performance loss (25-100%) if step_number is not passed as a template parameter to the integration kernel. Apparently the CUDA compiler cannot perform some optimizations if there is a if/else construct in a performance-critical part which cannot be evaluated at compile time. This branch keeps step_number as a template parameter but takes rest of the user parameters as uniforms (dt is no longer passed as a function parameter but as an uniform with the DSL instead). 2019-08-27 17:36:33 +03:00

5b686bc659 Fixed on/off switch for forcing and accretion, now forcing only happens for first 1000 steps (currently hard-coded), and accretion only happen after 1000 steps. 2019-08-20 23:12:42 +08:00

5b7408eb55 User config param overhaul complete, works. If I haven't missed anything, all fields and user parameters, and everything related to simulation can now be declared with the DSL. The only thing that you need to do is to fill the declared symbols with data, like with OpenGL and GLSL. 2019-08-19 18:43:16 +03:00

51cf1f1068 The C header is now generated from the DSL, stashing the changes just to be sure since I might overwrite something when updating the compilation scripts to work with this new scheme 2019-08-19 18:19:28 +03:00

bcdd827a4f Added a proper declarations for all user-specified uniform. Note: built-in uniforms are not correctly translated into CUDA 2019-08-19 17:05:56 +03:00
jpekkila
0208d55e4e Moved STENCIL_ORDER and NGHOST out of user-defined parameter as these are actually internal defines used to configure the built-in functions. Additionally, renamed all explicitly declared uniforms from dsx -> AC_dsx in the DSL in preparation for having clear connection between DSL uniforms and the library parameter handles created by the user (AcRealParam etc) 2019-08-19 16:40:47 +03:00
