Dear all, I want to solve a spherical problem within a multi patch environment, using Llama and the Thornburg04 coordinates.
For my equations I need several 1st and 2nd spatial derivatives in r direction. The GlobalDerivative thorn (part of Llama) provides a subroutine, that calculates the derivatives for certain directions: SUBROUTINE globalDiff_gv ( CCTK_POINTER_TO_CONST IN cctkGH, \ CCTK_INT IN dir, \ CCTK_REAL IN ARRAY var, \ CCTK_REAL OUT ARRAY dvar, \ CCTK_REAL IN ARRAY J_dadx, \ CCTK_REAL IN ARRAY J_dbdx, \ CCTK_REAL IN ARRAY J_dcdx, \ CCTK_REAL IN ARRAY J_dady, \ CCTK_REAL IN ARRAY J_dbdy, \ CCTK_REAL IN ARRAY J_dcdy, \ CCTK_REAL IN ARRAY J_dadz, \ CCTK_REAL IN ARRAY J_dbdz, \ CCTK_REAL IN ARRAY J_dcdz, \ CCTK_INT IN table_handle ) However, as far as I could see in the src code this only works for Cartesian coordinates or did I miss something? Does anyone know if there is a nice way to calculate such derivatives in r direction? Thanks a lot and best regards, Severin Frank _______________________________________________ Users mailing list [email protected] http://lists.einsteintoolkit.org/mailman/listinfo/users
