Description
Astrophysical systems, such as the solar atmosphere, can be modeled using various plasma descriptions. Magnetohydrodynamics (MHD) offers a less computationally expensive approach but may fail to capture small-scale phenomena, like magnetic reconnection, that require more sophisticated kinetic models. Since the regions requiring complex models are often much smaller than the rest of the domain, a coupled multiphysics approach can significantly reduce computational cost while maintaining the necessary level of realism.
In this work, we present an easy to use simulation framework implemented in Trixi.jl that can be used to adaptively couple different plasma models within a single domain. Our method is highly flexible, allowing for the coupling of diverse systems, such as a Vlasov model with an MHD model. This approach enables more accurate and efficient simulations of complex astrophysical phenomena. In this talk I will present a test case where we couple an MHD system with an Euler system.
