Struct t8_msh_file_node
Defined in File t8_cmesh_readmshfile.cxx
Struct Documentation

struct t8_msh_file_node
The nodes are stored in the .msh file in the format
$Nodes n_nodes // The number of nodes i x_i y_i z_i // the node index and the node coordinates j x_j y_j z_j ….. $EndNodes
The node indices do not need to be in consecutive order. We thus use a hash table to read all node indices and coordinates. The hash value is the node index modulo the number of nodes.
Public Functions
-
inline t8_msh_file_node()
Default constructor.
-
inline t8_msh_file_node(t8_gloidx_t id, std::array<double, 3> coords)
Constructor for non-parametric nodes.
- Parameters:
id – [inout] ID of the node.
coords – [inout] Coords of the node.
-
inline t8_msh_file_node(t8_gloidx_t id, std::array<double, 3> coords, std::array<double, 2> params, bool parametric, int entity_dim, t8_locidx_t entity_tag)
Constructor for parametric nodes.
- Parameters:
id – [inout] ID of the node.
coords – [inout] Coords of the node.
params – [inout] Parameters of the node in the parametric space.
parametric – [in] True if the node is parametric, false otherwise.#
entity_dim – [in] The dimension of the entity to which the node belongs.
entity_tag – [in] The tag of the entity to which the node belongs.
-
inline t8_msh_file_node(const t8_msh_file_node &other)
Copy constructor
- Parameters:
other – [in] The node to copy.
-
inline t8_msh_file_node(t8_msh_file_node &&other) noexcept
Move constructor.
- Parameters:
other – [in] The node to move.
-
inline t8_msh_file_node &operator=(const t8_msh_file_node &other)
Copy assignment operator.
- Parameters:
other – [in] The node to copy.
- Returns:
Reference to this node.
-
inline t8_msh_file_node &operator=(t8_msh_file_node &&other) noexcept
Move assignment operator.
- Parameters:
other – [in] The node to move.
- Returns:
Reference to this node.
Public Members
-
std::array<double, 2> parameters
Parameters of the node in the parametric space, if applicable. For example, for a point on a curve, this would be the parameter on the curve.
-
std::array<double, 3> coordinates
Coordinates of the node in physical space.
-
t8_gloidx_t index
The index of the node in the msh file.
-
bool parametric
True if the node is parametric, false otherwise. If true, the parameters are stored in the parameters array.
-
int entity_dim
The dimension of the entity to which the node belongs. For example, for a point on a curve, this would be 1.
-
t8_locidx_t entity_tag
The tag of the entity to which the node belongs. For example, for a point on a curve, this would be the tag of the curve.
