<br><h2>About patterns</h2>
|
||||
|
||||
The pattern describes a mesh to generate: positions of nodes within a
|
||||
geometrical domain and nodal connectivity of elements. As well, a
|
||||
pattern specifies the so-called key-points, i.e. nodes that will be
|
||||
located at geometrical vertices. Pattern description is stored in
|
||||
geometrical domain and nodal connectivity of elements. A
|
||||
pattern also specifies the so-called key-points, i.e. the nodes that will be
|
||||
located at geometrical vertices. The pattern description is stored in
|
||||
\<pattern_name\>.smp file.
|
||||
|
||||
The smp file contains 4 sections:
|
||||
|
||||
-# The first line holds the total number of the pattern nodes (N).
|
||||
-# The next N lines describe nodes coordinates. Each line holds 2
|
||||
coordinates of a node for 2D pattern or 3 cordinates for 3D pattern.
|
||||
Note, that for 3D pattern only relateive values in range [0;1] are
|
||||
valid for coordinates of the nodes.
|
||||
-# A key-points line: indices of nodes to be mapped on geometrical
|
||||
vertices (for 2D pattern only). An index n refers to a node described
|
||||
on an n-th line of section 2. The first node index is zero. For 3D
|
||||
pattern key points are not specified.
|
||||
-# The rest lines describe nodal connectivity of elements, one line
|
||||
for an element. A line holds indices of nodes forming an element. An
|
||||
index n refers to a node described on an n-th line of the section
|
||||
2. The first node index is zero. There must be 3 or 4 indices on a
|
||||
line for 2D pattern (only 2d elements are allowed) and 4, 5, 6 or 8
|
||||
indices for 3D pattern (only 3d elements are allowed).
|
||||
-# The first line indicates the total number of pattern nodes (N).
|
||||
-# The next N lines describe nodes coordinates. Each line contains 2
|
||||
node coordinates for a 2D pattern or 3 node cordinates for a 3D pattern.
|
||||
Note, that node coordinates of a 3D pattern can be defined only by relative values in range [0;1].
|
||||
-# The key-points line contains the indices of the nodes to be mapped on geometrical
|
||||
vertices (for a 2D pattern only). Index n refers to the node described
|
||||
on the n-th line of section 2. The index of the first node zero. For a 3D pattern the key points are not specified.
|
||||
-# The remaining lines describe nodal connectivity of elements, one line
|
||||
for each element. Each line holds indices of nodes forming an element.
|
||||
Index n refers to the node described on the n-th line of section 2.
|
||||
The first node index is zero. There must be 3 or 4 indices on each

|
||||
indices for a 3D pattern (only 3d elements are allowed).

The 2D pattern must contain at least one element and at least one
