This function creates and initializes the mesh, sbp, eqn, and opts objects

Inputs: opts: options dictionary

Outputs: mesh: an AbstractMesh. The concrete type is determined by the options dictionary sbp: an AbstractSBP. The concrete type is determined by the options dictionary eqn: an EulerData object opts: the options dictionary pmesh: mesh used for preconditioning, can be same object as mesh

Constructs a the EulerData object given a mesh, sbp, and options dictionary.

Used for submesh solves.

Inputs

• mesh

• sbp

• opts

Outputs

• mesh

• sbp

• eqn

• opts

• pmesh: currently, always the same as mesh

This function does post processing, if requested by the input options. Typical post processing includes calculation of errors, norms of important quantities, writing of files. etc.

Inputs: mesh sbp eqn opts

Given fully initialized mesh, sbp, eqn, opts, this function solves the Euler equations. The 4 object should be obtained from createObjects().

Specifically, it applies an initial condition and invokes a nonlinear solver according to the options dictionary.

Inputs: mesh: an AbstractMesh sbp: an AbstractSBP eqn: an AbstractEulerData opts: the options dictionary. This must be the options dictionary returned by createObjects(). Changing values in the options dictionary after calling createObjects() results in undefined behavior. pmesh: mesh used for preconditioning, can be same object as mesh. default value of mesh

This function checks the options in the options dictionary after default values have been supplied and throws exceptions if unsupported/incompatable options are specified

Inputs: opts: options dictionary

Outputs: none
