Function/Subroutine Documentation

real(DP),public Field_IcGrid2D_error_norm_check::numerical_error_norm1	(	type(Field_IcGrid2D),intent(in)	true_field,
		type(Field_IcGrid2D),intent(in)	num_field
	)

Calculates the error norm 1 for the numerical solution using exact solution.

Parameters:

[in]	true_field	The variable of derived type IcGrid Field which manages the exaact solution of a given field.
[in]	num_field	The variable of derived type IcGrid Field which manages the numerical solution of a given field.

real(DP),public Field_IcGrid2D_error_norm_check::numerical_error_norm2	(	type(Field_IcGrid2D),intent(in)	true_field,
		type(Field_IcGrid2D),intent(in)	num_field
	)

Calculates the error norm 2 for the numerical solution using exact solution.

Parameters:

[in]	true_field	The variable of derived type IcGrid Field which manages the exaact solution of a given field.
[in]	num_field	The variable of derived type IcGrid Field which manages the numerical solution of a given field.

real(DP),public Field_IcGrid2D_error_norm_check::numerical_error_norminfinity	(	type(Field_IcGrid2D),intent(in)	true_field,
		type(Field_IcGrid2D),intent(in)	num_field,
		logical,intent(in),optional	maxmin_info_flag
	)

Calculates the error norm 3 for the numerical solution using exact solution.

Parameters:

[in]	true_field	The variable of derived type IcGrid Field which manages the exaact solution of a given field.
[in]	num_field	The variable of derived type IcGrid Field which manages the numerical solution of a given field.
[in]	maxmin_info_flag	The flag indicating whether one needs the information about the location where the local difference with exact and numerical solution is maximum or minimum. The default flag value is false.
