CORHEL/MAS-TDM (6.0)CORona-HELiosphere/Magnetohydrodynamic Algorithm outside a Sphere Titov-Demoulin flux ropeModel DescriptionThis model combination from the CORona-HELiosphere (CORHEL) modeling suite (Predictive Science Inc.) consists of the MAS (Magnetohydrodynamic Algorithm outside a Sphere) model and the TDm flux rope designer. TDm designer is an interface that allows a user to interactively create a modied Titov-Demoulin (TDm) flux rope for insertion into realistic, observation-based background magnetic fields, then investigate the stability/instability properties with the MAS MHD model. At present, zero-beta eruptions generated by the TDm designer can be simulated with MAS (in the future full thermodynamic CME simulations will become available). Model Figure(s) :Model Inputs DescriptionModel inputs are provided through a GUI. The steps are as follows: 1) Select a date and time 2) Select an observatory source for the magnetic map 3) Select a region on the map 4) Select a polarity inversion line for the flux rope 5) Select the foot points of the flux rope and flux-rope parameters: Axis apex height, fractional width, fractional field strength relative to background, preserve magnetogram flux (yes/no) Model Outputs DescriptionThe interface creates a tarball with the file or performing the MHD simulation on a computer where CORHEL-6 is installed. Approximate run times for different processor counts are provided. After the simulation run is performed, a diagnostics tarball is created. After opening the tarball, the user opens an html page that guides the user through the results (movies of the evolution, run histories, etc.). Model CaveatsThe zero-beta model is useful for exploring flux-rope stability, and properties such as the initial trajectory of the erupting flux rope.
