They are compatible with a tabulated equation of state suitable for simulations of core-collapse supernovae.\nThis allows us to perform characteristic slope limiting, which has been shown\nto be more efficient than limiting directly on the conserved variables, without the need\nfor numerically diagonalizing the flux Jacobian.\nThis has been implemented in [thornado](https://github.com/endeve/thornado), and initial\n1D tests have been performed, showing the superior performance of the characteristic limiter.\nWe hope that this work will improve the fidelity of CCSN simulations.\n\nThe work done here will be extended to include 2D tests and published soon after.\n\nExample of a test Riemann problem showing the significant improvements of characteristic limiting:\n![plot](paper/figures/characteristic_cw.png)\n","project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fastrobarker%2Fdghydro_thesis_utk","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Fastrobarker%2Fdghydro_thesis_utk","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fastrobarker%2Fdghydro_thesis_utk/lists"}
