Return the magnitude of a vector

Add a requirement value to the dictionary. If the value is already defined with another value, it will raise an exception, unless over

Interpolate a Field2D to a new CELL_LOC with interp_to. Communicates to set internal guard cells. Boundary guard cells are set by extrapolating from t

Note: Here rather than in header to avoid many deprecated warnings Remove in future and make this function pure virtual

Convert a sympy expression to a string for BOUT++ input

Laplacian in X-Z

! Initialise BOUT++ Inputs ------ The command-line arguments argc and argv are passed by reference, and pointers to these will be stored i

Serial code

Fourier filter in z with zmin

Calculates [f,g] symbolically

Estimate the magnitude of an expression

Get all the available methods for this direction and turn it from a collection of strings to a collection of tuples of the direction, order, and strin
