Geophysical and Astrophysical Simulations in QuickField. A recording of a free webinar, one of Dr. Claycomb’s webinars, held at www.quickfield.com on February 24, 2011. Dr. James Claycomb who recently spoke about Biophysical Simulations using QuickField, continues by this new webinar about geophysical and astrophysical simulations in QuickField. Topics include the simulation of heat transfer in the Earth’s mantle, crust and near hydrothermal vents. Astrophysical magnetic sources are simulated including geomagnetic field sources, the Jovian magnetic field and its interaction with Europa. Tidal stresses are simulated including the stress distribution in the ice sheet of Europa due to tidal interaction with Jupiter. More information on QuickField, videos and live webinars are to be found at www.quickfield.com. Part 1/5. Contents. Modeling Geomagnetic field in Magnetostatic calculation in axial symmetry. Geometry sketch, modeling Earth in geometry and assigning its properties in QuickField. Permeability, current density, field source, coercive force of a magnet. Boundary conditions. Finite elements mesh. Results, approximation of earth magnetic field, DC magnetic field. Flux density, contour plots. Currents flowing in the mantle. How changing the properties affect the resulting picture.
