Detailed Description

Module definition of Type_Vector.

Function/Subroutine Documentation

elemental real(r8p) function, public data_type_vector::sq_norm ( type(type_vector), intent(in) vec )

Function for computing the square of the norm of a vector.

The square norm if defined as $ N = x^2 + y^2 + z^2$ .

Parameters

[in] vec Vector.

elemental real(r8p) function, public data_type_vector::norml2 ( type(type_vector), intent(in) vec )

Function for computing the norm L2 of a vector.

The norm L2 if defined as $N = \sqrt {x^2 + y^2 + z^2 }$ .

Parameters

[in] vec Vector.

Definition at line 420 of file Data_Type_Vector.f90.

elemental type(type_vector) function, public data_type_vector::normalize ( type(type_vector), intent(in) vec )

Function for normalizing a vector.

The normalization is made by means of norm L2. If the norm L2 of the vector is less than the parameter smallR8P the normalization value is set to normL2(vec)+smallR8P.

Parameters

[in] vec Vector to be normalized.

		type(type_vector), intent(in)	pt2,
		type(type_vector), intent(in)	pt3,
		type(type_vector), intent(in)	pt4
	)

Function for calculating the normal of the face defined by 4 points vector pt1, pt2, pt3 and pt4.

The convention for the points numeration is the following:

 |          |
 |          |
 |          |
 |          |
4.----------.3

The normal is calculated by the cross product of the diagonal d13 for the diagonal d24: d13 x d24. The normal is normalized if the variable 'norm' is passed (with any value).

Parameters

[in]	norm	If 'norm' is passed as argument the normal is normalized.
[in]	pt1	First face point.
[in]	pt2	Second face point.
[in]	pt3	Third face point.
[in]	pt4	Fourth face point.

The normal is calculated by the cross product of the side s12 for the side s13: s12 x s13. The normal is normalized if the variable 'norm' is passed (with any value).

Parameters

[in]	norm	If 'norm' is passed as argument the normal is normalized.
[in]	pt1	First face point.
[in]	pt2	Second face point.
[in]	pt3	Third face point.
