CellMat (class)

Method code available at https://github.com/Eomys/pyleecan/tree/master/pyleecan/Methods/Mesh/CellMat

class CellMat(connectivity=[], nb_cell=0, nb_node_per_cell=0, indice=[], interpolation=-1, init_dict=None, init_str=None)[source]

Bases: pyleecan.Classes._frozen.FrozenClass

Define the connectivity under matricial format containing one type of element (example: only triangles with 3 nodes).

VERSION = 1
add_cell(pt_indice, new_ind)

Add a new element

Parameters
  • self (CellMat) – an CellMat object

  • new_ind (int) – an new cell indices

  • pt_indice (ndarray) – connectivity

Returns

is_created – False if the element already exist or if it is not possible to add the element

Return type

bool

get_connectivity(cell_indice=None)

Return the connectivity of one cell.

Parameters
  • self (CellMat) – an CellMat object

  • cell_indice (int) – the indice of a cell. If None, return all cells.

Returns

connect_select – Selected cell connectivity. Return None if the tag does not exist

Return type

ndarray

get_node2cell(node_indice)

Return all indices of cells containing a node.

Parameters
  • self (CellMat) – an CellMat object

  • node_indice (int) – a node indice

Returns

node_to_cell – Indices of cells containing the node

Return type

ndarray

is_exist(connectivity)

Check the existence of a cell defined by a connectivity (vector of points indices). The order of points indices does not matter.

Parameters
  • self (CellMat) – an CellMat object

  • connectivity (ndarray) – an array of node tags

Returns

True if the element already exist

Return type

bool

save(save_path='', is_folder=False)

Save the object to the save_path

Parameters
  • self – A pyleecan object

  • save_path (str) – path to the folder to save the object

  • is_folder (bool) – to split the object in different files: separate simulation machine and materials

copy(**kwargs)

Return a copy of the class

get_logger()

Get the object logger or its parent’s one

Parameters

obj – A pyleecan object

Returns

logger – Pyleecan object dedicated logger

Return type

logging.Logger

compare(other, name='self')[source]

Compare two objects and return list of differences

as_dict(**kwargs)[source]

Convert this object in a json serializable dict (can be use in __init__). Optional keyword input parameter is for internal use only and may prevent json serializability.
