The C core stores pointers to the Lua string passed when login in to an account. However Lua's strings are only valid until they are popped from stack. Thus once...

calc_every != 0 does not properly work during CCTK_EVOL

2

Currently Kranc always inserts this fragment (in Kranc/Tools/CodeGen/CodeGenCalculation.m) ``` ConditionalOnParameterTextual[ "cctk_iteration % " functionName "_calc_every != " functionName "_calc_offset", "return;\n"], ``` which is however not correct in CCTK_EVOL since there...

Kranc's automated boundary code for non-MoL code looks like this `Auxiliary/Cactus/SourceFiles/Kranc.cc`: ```C++ /********************************************************************* * GetBoundaryWidths *********************************************************************/ void GetBoundaryWidths(cGH const * restrict const cctkGH, CCTK_INT nboundaryzones[6]) { CCTK_INT is_internal[6]; CCTK_INT is_staggered[6];...

Kranc does not allow grid functions that start with the letter u

7

Taking the http://kranccode.org/SimpleWave.m example and adding `ut` to `groups`: ``` groups = {{"evolved_group", {phi, pi, ut}}}; ``` produces the following error: ``` Using Kranc installation at /home/rhaas/postdoc/gr/cactus/ET_trunk/repos/Kranc/Bin/.. Mathematica 11.0.0 for...

for a refinement level that evaluates every rl_every the routines are called in EVOL whenever (cctk_iteration-1) % rl_every is zero (ie the iteration after cctk_iteration % rl_every was valid). Thus...

Kranc's Differencing.h fails to compile if KRANC_DIFF_FUNCTIONS is defined

1

the error is not passing the correct number of arguments: ``` In file included from /mnt/data/rhaas/postdoc/gr/ET_trunk/configs/sim/build/ML_BSSN/ML_BSSN_Advect.cc:14:0: /mnt/data/rhaas/postdoc/gr/ET_trunk/arrangements/McLachlan/ML_BSSN/src/Differencing.h: In function 'double PDupwindNthfdOrder23_impl(const double*, double, ptrdiff_t, ptrdiff_t, ptrdiff_t, ptrdiff_t, ptrdiff_t)': /mnt/data/rhaas/postdoc/gr/ET_trunk/arrangements/McLachlan/ML_BSSN/src/Differencing.h:1043:56: error:...

It would be very nice if Kranc supported four-tensors. Ideally one could declare a,b,c,... indices to be 4 indices but i,j,k,.. to be 3 indices (helps with say PD to...

McLachlan has incorrect READ declarations for presync

1

ET issue https://bitbucket.org/einsteintoolkit/tickets/issues/2526/mclachlan-has-incorrect-read-declarations describes an issue observed in McLachlan. However this is ultimately due to a problem in Kranc. Pull request https://github.com/ianhinder/Kranc/pull/155 proposes a fix. Could the be included in...

github no longer supports the `git://` protocol and requests time out. Instead one must use `https://`. Pull request [https://github.com/ianhinder/Kranc/pull/153/files](https://github.com/ianhinder/Kranc/pull/153/files) implements this in the tutorial web-page.
