Llama Multi-Block Infrastructure publicly available
The Llama Multi-Block Infrastructure for Cactus is now publicly available under the GNU General Public License. Llama provides three-dimensional multi-block capability for Cactus-based simulations that can be combined with Carpet’s adaptive mesh refinement functionality. Llama decomposes the domain into multiple (potentially overlapping) blocks with different local coordinate systems. This allows e.g. spherical domains, spherical excision, adaptive radial/angular resolution, etc., without incurring coordinate singularities.
Llama provides several patch systems suitable for single and binary objects in relativistic astrophysics, and is well integrated with the Einstein Toolkit . Llama was already used for several publications , and we believe the code is ready to be used in other projects. We are seeking volunteers to help us add tutorials and documentation, improve error messages, and generally shake down and brush up the code for a future inclusion in the Einstein Toolkit.
To aid others in getting started using Llama, we will be hosting a virtual workshop where we provide an overview of the code and answer questions. Details will be announced shortly.
Llama constitutes the fruit of a significant effort of several people over several years. We make Llama public to help modernize the computational tools used in our community, and in the hope to boost Llama itself by inviting contributions from everybody. We ask you to acknowledge our effort by following the citation guidelines described on .
