  • 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. jpekkila 2019-06-26 13:33:03 +03:00

  • 8191c47fa0 Scetching the helical forcing. Miikka Vaisala 2019-06-25 19:04:53 +08:00
  • 912dffca4f Renamed old single-GPU-only headers in core/kernels to avoid confusion. Only kernels.cuh is used for reductions, integration and boundary conditions at the moment. jpekkila 2019-06-25 13:58:59 +03:00

  • f2a33bf4f8 Starting with derivatives for upwinding. Miikka Vaisala 2019-06-21 16:53:04 +08:00
  • a5ab388af7 Fixed a compilation error when not using entropy. This is a temporary workaround. There is no model solution for hydro only, therefore autotesting will break if entropy is not used. Note: LINDUCTION, LENTROPY and other logical flags are duplicated in both astaroth.h and stencil_process.sps. These flags are not linked and there will be errors and weird behaviour if a flag is set in one file and not in another. jpekkila 2019-06-19 20:18:25 +03:00
  • 2310186c71 Added a skeleton function for updating an arbitrary block inside the computational domain instead of the whole mesh jpekkila 2019-06-19 19:43:46 +03:00

  • 4ee772cf5d Set the minimum gcc version required in CMakeLists.txt jpekkila 2019-06-19 16:57:47 +03:00
  • a7515fbbd7 Made the simple forcing to scale with dt s.t. it does not explode so easily jpekkila 2019-06-19 16:34:23 +03:00
  • f3cbc4984c Enabled toy forcing by default for testing purposes. Note that there are two LFORCING switches at the moment: one in astaroth.h and one in acc/mhd_solver/stencil_process.sps. The switches are not linked and the tests fail or simulations generate unexpected results if both switches are not set to the same value. This will be fixed in the near future. jpekkila 2019-06-19 16:14:46 +03:00
  • 6da061b854 Fixed a bug in the Astaroth compiler: the boilerplate code for kernels was generated for all nested compound statements instead of just the top-level one jpekkila 2019-06-19 16:10:29 +03:00
