Dipole Collapse and Dynamo Waves in Global Direct Numerical Simulations
Dipole Collapse Dynamo Waves Global Direct Numerical Simulations
2012/2/23
Magnetic fields of low-mass stars and planets are thought to originate from self-excited dynamo action in their convective interiors. Observations reveal a variety of field topologies ranging from lar...
Numerical Modelling of the Topographic Wetness Index: An Analysis at Different Scales
Resolution DEM Grid Size Wetness Index
2013/3/7
A variety of landscape properties have been modeled successfully using topographic indices such as topographic wetness index (TWI), defined as ln(a/tanβ), where a is the specific upslope area and β is...
A Fourth Order Improved Numerical Scheme for the Generalized Burgers—Huxley Equation
Burgers-Huxley Finite-Difference Method Modified Predictor-Corrector
2013/1/30
A fourth order finite-difference scheme in a two-time level recurrence relation is proposed for the numerical solution of the generalized Burgers--Huxley equation. The resulting nonlinear system, whic...
