Function Documentation

read_initial_conditions()

void read_initial_conditions	(	const char *	filename,
		int	NUM,
		double **	y_host,
		double **	variable_host
	)

Reads initial conditions for IVPs from binary file.

Parameters

[in]	filename	the file to read from
[in]	NUM	the number of IVP initial conditions to read
[in,out]	y_host	Address of the host state vector pointer. This is initialized and populated by this method
[in,out]	variable_host	Address of the host pressure/density pointer. This is initialized and populated by this method

Note: the data file is expected to be in the following format:
time, Temperature, Pressure, mass fractions (State #1)
time, Temperature, Pressure, mass fractions (State #2) ...
