CheckIntegrity()

class UtWriter

Bases: WriterBase

Class to write an ut file, and the files of the data defined in this ut file. This class can generate a .ut, .geof, .ctnod, .node, .integ to vizualise finite element computational results

AttachData(data_node, data_ctnod={}, data_integ={}, Nnode=None, Nint=None)

Attach fields to the writer

Parameters:

• data_node (dict) – primal fields, defined at the vertices of the mesh

• data_ctnod (dict, optional) – dual fields, defined at the vertices of the mesh, by default {}

• data_integ (dict, optional) – dual fields, defined at the integration points of the mesh, by default {}

• Nnode (int, optional) – number of nodes, by default None

• Nint (int, optional) – number of integration points, by default None

AttachDataFromProblemData(problemData, tag, Nnode=None, Nint=None)

Attach the fields defined in a problemData to the writer

Parameters:

• problemData (ProblemData) – description of a physical problem

• tag (str) – solution name to attache to the writer

• Nnode (int, optional) – number of nodes, by default None

• Nint (int, optional) – number of integration points, by default None

AttachMesh(mesh)

Attach mesh to writer

Parameters:

mesh (Mesh) – mesh to attach to writer

AttachSequence(timeSequence)

Attach the time sequence to the writer

Parameters:

timeSequence (np.ndarray) – time sequence to attach to the writer

Close()

GetBaseName()

Returns the file name to write without extension

Returns:

file name to write without extension

Return type:

str

GetFolder()

Returns folder where the file is written

Returns:

folder where the file is written

Return type:

str

InitWrite(writeGeof, geofName=None, skipCtnod=False)

Initialize the written files

Parameters:

• writeGeof (bool) – if True, the mesh is written in Geof format

• geofName (str, optional) – name of the mesh file, by default None

• skipCtnod (bool, optional) – if True, the dual quantities will not be exported at the verticies, by default False

Returns:

nodeFile, ctnodFile and integFile initialized

Return type:

_io.TextIOWrapper, _io.TextIOWrapper, _io.TextIOWrapper

WriteMesh()

Write mesh to file in Geof format

WriteTimeStep(nodeFile, ctnodFile, integFile, timeSequenceStep, skipCtnod=False)

Write one time step into initialized .ut, .ctnod, .node and .integ files

Parameters:

• nodeFile (_io.TextIOWrapper) – .node file containing primal fields at verticies
