Description
We present among the first black hole-neutron star merger simulations with full and improved microphyiscal treatment on the GPU-accelerated code AthenaK. As a test suite we look at the standard diagnostics, such as gravitational waves, ejecta properties, the post-merger disk and nucleosynthesis yields. We find that our low-resolution results compare well against the literature results obtained with legacy codes. This small study demonstrates that we are able to push to even higher resolutions and larger batches of simulations, gaining results in much shorter time compared to traditional codes, in the exascale era.
