Homotopy
This page documents the functions that compute the dissipation function needed by homotopy methods
EulerEquationMod.calcHomotopyDiss — Method.Calculate a first order accurate dissipation to use as a homotopy function
Inputs: mesh: a DG mesh sbp: an SBP operator eqn: an EulerData object opts: options dictionary
Inputs/Outputs: res: 3D array to store the homotopy function in
Note eqn.res is not modified by this function.
Aliasing restrictions: none
EulerEquationMod.getLambdaMax — Method.Calculate the maximum wave speed for a given state
Inputs: params: a ParamType qL: a vector of conservative variables at a node dir: a direction vector, length 2 in 2D and 3 in 3D
Outputs: lambda_max: the maximum wave speed
Aliasing restrictions: none
PDESolver.evalHomotopy — Function.This function calls the appropriate homotopy function for the Euler module.
