From 7c50d21a280caf9329ceaac74909a92ae459c816 Mon Sep 17 00:00:00 2001 From: Ian Hinder Date: Thu, 19 May 2011 15:04:03 +0200 Subject: McLachlan_BSSN.m: Change from old TensorTools to new Kranc Jacobians for MP The Jacobian gridfunction groups are no longer hard-coded into McLachlan, and the Coordinates thorn is no longer inherited. Instead, the user must use GenericFD parameters to specify the Jacobian to use. The new Kranc Jacobian implementation allows a single map to be specified on which the Jacobian is not applied, which greatly improves performance in typical multipatch simulations. To use the new Jacobian method with Llama, set GenericFD::jacobian_group = "Coordinates::jacobian" GenericFD::jacobian_derivative_group = "Coordinates::jacobian2" GenericFD::jacobian_identity_map = 0 --- ML_BSSN_Test/test/ML_BSSN_MP_O8_bh.par | 4 ++++ 1 file changed, 4 insertions(+) (limited to 'ML_BSSN_Test') diff --git a/ML_BSSN_Test/test/ML_BSSN_MP_O8_bh.par b/ML_BSSN_Test/test/ML_BSSN_MP_O8_bh.par index 6be8ef8..995f730 100644 --- a/ML_BSSN_Test/test/ML_BSSN_MP_O8_bh.par +++ b/ML_BSSN_Test/test/ML_BSSN_MP_O8_bh.par @@ -23,6 +23,10 @@ ML_BSSN_MP_O8::my_rhs_boundary_condition = "static" ML_BSSN_MP_O8::EpsDiss = 0.1 +GenericFD::jacobian_group = "Coordinates::jacobian" +GenericFD::jacobian_derivative_group = "Coordinates::jacobian2" +GenericFD::jacobian_identity_map = 0 + Boundary::radpower = 2 ############################################################# -- cgit v1.2.3
