Applications are now open for an upcoming workshop, “Simulating Extreme Spacetimes with SpEC and SpECTRE II: Summer school and developers’ meeting”, Jul 19 – 23, 2027, at ICERM, Brown University, US (https://icerm.brown.edu/program/topical_workshop/tw-27-ses2).
The Simulating eXtreme Spacetimes (SXS) collaboration has managed the development of two distinct numerical relativity codes to enable high-fidelity simulations of compact object mergers: (i) the Spectral Einstein Code (SpEC) based on pseudospectral methods, and (ii) the open-source code SpECTRE, an hp-adaptive discontinuous Galerkin scheme for relativistic astrophysics. Our weeklong program includes two related activities:
(i) a SpECTRE community workshop and
(ii) a SpEC and SpECTRE developers meeting.
Our SpECTRE workshop aims to provide graduate students, postdocs, and faculty with the tools to install, run, and contribute to the open-source code SpECTRE. The open-source code SpECTRE is a relativistic astrophysics code for simulating neutron star mergers, core-collapse supernovae, and gamma-ray bursts. Our SpECTRE workshop will include both lectures and hands-on sessions. Lecture topics will include the generalized harmonic formulation of the Einstein field equation, general relativistic hydrodynamics, the discontinuous Galerkin method with finite volume sub-cells, the Cauchy characteristic evolution method, and the use of coding agents for code development. There will also be ample opportunity for students and postdocs to interact with senior participants and lecturers of the ICERM workshop program. The code developers’ meeting will bring together researchers who are actively developing SpEC, SpECTRE, and accompanying software for interacting with publicly available simulation datasets such as gravitational waveforms. Both events will be in-person, with streaming options available for lectures. ICERM will be able to offer limited funding for some participants.
The application deadline is February 28, 2027.
