On the verification of adaptive three-dimensional multiresolution computations of the magneto hydrodynamic equations

International audienceMagneto hydrodynamics is an important tool to study the dynamics of Space Physics. In this context, we introduce a three-dimensional magneto hydrodynamic solver with divergence-cleaning in the adaptive multiresolution CARMEN code. The numerical scheme is based on a finite volume discretization that ensures the conservation of physical quantities. The adaptive multiresolution approach allows for automatic identification of local structures in the numerical solution and thus provides an adaptive mesh refined only in regions where the solution needs more improved resolution. We assess the three dimensional magnetohydrodynamic CARMEN code and compare its results with the ones from the well-known FLASH code
