[Einstein Toolkit] #1078: ignore non-evolved points in check_GRHydro_C2P_failed

#1078: ignore non-evolved points in check_GRHydro_C2P_failed -----------------------------------+---------------------------------------- Reporter: rhaas | Owner: Type: enhancement | Status: new Priority: minor | Milestone: Component: EinsteinToolkit thorn | Version: Keywords: GRHydro | -----------------------------------+---------------------------------------- The attached patch interfaces GRHydro with Carpet/CarpetEvolutionMask to not abort a run if a con2prim failure happens at points that are not active in the sense that they should not be eg. visualized. CarpetEvolutionMask computes these points by taking the restricted region and modifying it to take buffer zones and ghost zones for prolongation into account. The proposed patch uses Cray pointers (see https://trac.einsteintoolkit.org/ticket/1065) since the Cactus flesh routine to CCTK_VarDataPtr (for Fortran) uses them as well. This requires extra switches for compilers to compile. For gcc the switch is "-fcray- pointer" for intel adding "-safe_cray_ptr" might help efficiency. -- Ticket URL: <https://trac.einsteintoolkit.org/ticket/1078> Einstein Toolkit <http://einsteintoolkit.org> The Einstein Toolkit

[Einstein Toolkit] #1134: Adams-Bashforth time integrator

#1134: Adams-Bashforth time integrator -----------------------------------+---------------------------------------- Reporter: eschnett | Owner: Type: enhancement | Status: new Priority: major | Milestone: Component: EinsteinToolkit thorn | Version: Keywords: | -----------------------------------+---------------------------------------- The attached patch implements Adams-Bashforth time integration in MoL and provides a WaveToy test case. Adams-Bashforth integrators calculate a high-order extrapolation with a single RHS evaluation by combining it with results from previous time steps. This requires multiple time levels for the RHS variables. -- Ticket URL: <https://trac.einsteintoolkit.org/ticket/1134> Einstein Toolkit <http://einsteintoolkit.org> The Einstein Toolkit

[Einstein Toolkit] #940: McLachlan dissipation error

#940: McLachlan dissipation error -----------------------------------+---------------------------------------- Reporter: eschnett | Owner: Type: defect | Status: new Priority: major | Milestone: Component: EinsteinToolkit thorn | Version: Keywords: | -----------------------------------+---------------------------------------- A kind person tells me: I wanted to mention what appears to be a mistake in your dissipation calculation. If you refer to Kreiss-Oliger, or equivalently to Dissipation/src/apply_dissipation.F77, you find that there is a sign flip at certain orders. For example, 3rd order dissipation to be used with 2nd order differencing, and 7th order dissipation to be used with 6th order differencing, both need a negative coefficient. But you don't appear to have such a minus sign (unless I missed it), and your parameter epsdiss is constrained to be positive. It looks to me like PDdissipationNth needs to be multiplied by something like (-1)^(fdOrder/2). -- Ticket URL: <https://trac.einsteintoolkit.org/ticket/940> Einstein Toolkit <http://einsteintoolkit.org> The Einstein Toolkit

#815: Outlfow thorn in incoming -------------------------+-------------------------------------------------- Reporter: rhaas | Owner: Type: enhancement | Status: new Priority: optional | Milestone: Component: Other | Version: Keywords: | -------------------------+-------------------------------------------------- Hello all, as discussed in the last phone call, the GT Outflow thorn has been put into incoming (http://svn.einsteintoolkit.org/incoming/Outflow). From the docs: {{{ Outflow calculates the flow of rest mass density across a SphericalSurface, eg. and apparent horizon or a sphere at ``infinity''. }}} It has documentation, test-cases and publications using it (http://arxiv.org/abs/1201.4389). Ok to include in EinsteinAnalysis? -- Ticket URL: <https://trac.einsteintoolkit.org/ticket/815> Einstein Toolkit <http://einsteintoolkit.org> The Einstein Toolkit

[Einstein Toolkit] #1003: Add optional support for CarpetEvolutionMask to GRHydro

#1003: Add optional support for CarpetEvolutionMask to GRHydro -----------------------------------+---------------------------------------- Reporter: rhaas | Owner: Type: enhancement | Status: new Priority: minor | Milestone: Component: EinsteinToolkit thorn | Version: Keywords: GRHydro | -----------------------------------+---------------------------------------- the attached patch adds access to CarpetEvolutionMask's evolution mask to GRHydro. CarpetEvolutionMaks tracks which points on each level contribute to the final answer, roughly speaking anything that would show up in a call to the interpolators. The functional change to GRHydro is trivial (just a parameter, a GF access and a cycle in the routine that checks for C2P failures). However getting the equivalent of CCTK_VarDataPtr to work in Fortran turned out to be ugly. Better solutions are very welcome. Desired features are: * easy to use * not error prone * allows to run GRHydro without CarpetEvolutionMask (this means inheriting won't work) * low memory footprint -- Ticket URL: <https://trac.einsteintoolkit.org/ticket/1003> Einstein Toolkit <http://einsteintoolkit.org> The Einstein Toolkit
