Methods¶

__init__¶

• Source: GitHub

def sdynpy.Exodus.__init__(self, filename, mode='r', title=None, num_dims=None, num_nodes=None, num_elem=None, num_blocks=None, num_node_sets=None, num_side_sets=None, clobber=False)

Initialize self. See help(type(self)) for accurate signature.

close¶

• Source: GitHub

def sdynpy.Exodus.close(self)

extract_sharp_edges¶

• Source: GitHub

def sdynpy.Exodus.extract_sharp_edges(self, *args, **kwargs)

get_block_surface¶

• Source: GitHub

def sdynpy.Exodus.get_block_surface(self, block_id, keep_midside_nodes=False, warn=True)

Gets the node indices and element connectivity of surface elements

This function “skins” the element block, returning a list of node indices and a surface connectivity matrix.

Parameters¶

• block_id : int The ID number of the block that will be skinned.

• keep_midside_nodes : bool Specifies whether or not to keep midside nodes in the surface mesh. Default is False.

• warn : bool Specifies whether or not to warn the user if the block ID doesn’t have a skinning method defined for its element type. Default is True.

Returns¶

• element_block_information : list A list of tuples of element information. These data are element_type, node_indices, block_surface_connectivity, and block_surface_original_elements. The element_type is a string representing the new block element type (‘quad4’,‘tri3’,etc.). The node_indices can be used as an index into the coordinate or nodal variable arrays to select nodes corresponding to this block. The block_surface_connectivity represents the connectivity array of the surface faces of the block. Values in this array correspond to indices into the node_indices array. To recover the connectivity array in the original node indices of the exodus file, it can be passed through the node_indices as node_indices[block_surface_connectivity]. The block_surface_original_elements array shows the original element indices of the block that each surface came from. This can be used to map element variables to the new surface mesh. This list will normally be length 1 unless an element type is processed that has two different surface elements in it (e.g. wedges have tris and quads)

Parameters¶

• name_or_index : str or int Name or Index of the nodal variable that is desired. If type(name_or_index) == str, then it is assumed to be the name. If type(name_or_index) == int, then it is assumed to be the index.

• step : int Time step at which to recover the nodal variable

• values : array-like A 1d array consisting of the variable values for each node at the specified time step.

Notes¶

If step is not a valid index for the time vector, the time vector will be expanded so that it is.

set_time¶

• Source: GitHub

def sdynpy.Exodus.set_time(self, step, value)

Sets the time value of a given step in the exodus file

Parameters¶

• step : int The index in the time vector to set to value

• value : float A real number to set the value of the specified index in the time vector to.

Notes¶

If step is not a valid index for the time vector, the time vector will be expanded so that it is.

set_times¶

• Source: GitHub

def sdynpy.Exodus.set_times(self, values)

Sets the time vector for the exodus file

Parameters¶

• values : array-like A 1-dimensional array that has the time step values as it’s entries

Notes¶

If the vector is longer than the current time step vector, it will be expanded. If the vector is shorter than the current time step vector, only the first len(values) entries of the time vector will be assigned.

triangulate_surface_mesh¶

• Source: GitHub

def sdynpy.Exodus.triangulate_surface_mesh(self)

Triangulate a surface mesh for plotting patches

This function generates a triangle mesh for each block in the model if it can. If there are more than 3 nodes per element in a block, and the triangulation scheme hasn’t been defined in pyexodus.mesh_triangulation_array, it will be skipped.

Parameters¶

• None

Returns¶

• triangulated_mesh_info : list A list of tuples containing block id, node_indices, triangulated connectivity, and original block elements
