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

0c63d55fd7 Worked around a compiler bug in CUDA 9.1, which caused an "Internal Compiler Error (codegen): "there was an error in verifying the lgenfe output!". Apparently the compiler got confused by overloaded is_valid() if the input parameter was not passed as a reference in both cases. 2019-06-29 10:49:15 +03:00

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

9b45716186 Modified user.h such that astaroth compiles with Pencil Code. Note that this is a temporary fix: we should ultimately set the default parameters for all the logical switches in astaroth.h and let the user redefine them at will, either with the DSL or with user.h 2019-06-27 18:12:14 +03:00

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

8ca09668c1 Added an advance notice about LINDUCTION to be renamed to LMAGNETIC in the near future throughout the project. LMAGNETIC would be better name since he define is used to enable the magnetic field. 2019-06-27 13:28:52 +03:00

75fb756ad4 Autoformatted with clang-format. Clang-format does not support indented defines as far as I know, so this will have to do. The alternative would be not to use autoformatting at all (or some other tool). 2019-06-27 13:16:41 +03:00

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.

cda17c9b08 VERBOSE_PRINTING flag is now globally used in the whole program and should be used to suppress development/debugging-related printing. Also added comments to the new interface function acCheckDeviceAvailability and made it free from side effects. 2019-06-26 18:50:15 +03:00

6bfc5f04f7 Added tighter bounds for gcc and nvcc versions. There was a bit of an chicken-and-egg issue: we need gcc 6.0 in order to get bug 48891 (see gcc bugzilla) fixed, but cuda < 9 supports gcc only up to 5.3. This is not a perfect solution, f.ex. ubuntu 16.04 ships with gcc 5.4 but with the fix backported from later versions so in practice that would also work but is not accepted anymore. 2019-06-26 13:33:03 +03:00

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.
