#2915: Include CapyrX: a GPU-accelerated multipatch infrastructure

Reporter: Beyhan Karakaş Status: open Milestone: ET_2026_05 Version: Type: enhancement Priority: major Component: EinsteinToolkit thorn

Comment (by Roland Haas):

Adding all present thorns (and applying the NewRadX patch for multipatch support) I get a test failure:

``` multipole (from CapyrX_WaveToy) ```

with error message:

``` Error: Implementation 'COORDBASE' not activated. This implementation is required by activated thorn(s): Multipole (implementing multipole) This implementation is provided by compiled thorn(s): CoordBase Add a thorn providing this implementation to the ActiveThorns parameter. Error: Implementation 'GRID' not activated. This implementation is required by activated thorn(s): Multipole (implementing multipole) This implementation is provided by compiled thorn(s): CartGrid3D Add a thorn providing this implementation to the ActiveThorns parameter.
