patchComponent Struct Reference

Detailed Description

Struct which represents a certain component (interior, face, egde, corner) of a particular patch.

This struct is a generalization of patchSide and of patchCorner.

Member Function Documentation

locationForDirection()

boxComponent::location locationForDirection ( index_t  direction ) const

inherited

Gets the location for the direction

If the result value is begin, then the component is characterized by \( x_i = 0 \) If the result value is end, then the component is characterized by \( x_i = 1 \) If the result value is begin, then the component is characterized by \( x_i \in (0,1) \)

Parameters

direction

The index \( i \) from above

setLocationForDirection()

void setLocationForDirection ( index_t  direction, boxComponent::location  par  )

inherited

Sets the location for the direction

See locationForDirection

Parameters

direction	The index \( i \) from above
par	See locationForDirection

Member Data Documentation

m_index

index_t m_index

privateinherited

The index defines the component.

If the index is written as trinary number with digits 0, 1, 2 each position names one of the spatial dimensions and values are: 0=interior, 1=begin, 2=end (cf location)

So, in 2D (m_total_dim=2), we have indeces [00]=0 to [22]=8

[00] = 0 ... interior
[01] = 1 ... left edge
[02] = 2 ... right edge
[10] = 3 ... lower edge
[20] = 6 ... upper edge
[11] = 4 ... lower-left corner
etc., where [ab]=3*a+b

In 3D (m_total_dim=3), we have indeces [000]=0 to [222]=26

[000] =  0 ... interior
[001] =  1 ... west face
[002] =  2 ... east face
[010] =  3 ... south face
[020] =  6 ... north face
[100] =  9 ... front face
[200] = 18 ... back face
[011] =  4 ... south-west edge
[222] = 26 ... back-north-east corner
etc., where [abc]=9*a+3*b+c
