Muscat.IO.RstReader module

rst based ansys mesh reader. returns an unstructured mesh (class from BasicTools)

CheckIntegrity(GUI: bool = False)

ReadRst(fileName: str, time: float64 = None, timeIndex: int64 = None, fromElementalNodalToNodal=True)

Function mesh and solution fields (noda, elemental and elemental nodal) from a rst file

Parameters:

• fileName (str, optional) – name of the file to be read, by default None

• time (float, optional) – time at which the field is read, by default None

• timeIndex (int, optional) – time index at which the field is read, by default None

Returns:

output Mesh object containing the results

Return type:

Mesh

class RstReader

Bases: ReaderBase

Rst Reader class

GetAvailablePostResults() → List

GetAvailableResultsAndOperators() → List

Returns the available results and its operator name

Returns:

contains a namedTuple with the results. attributes are name, operator_name, native_location, n_components

Return type:

list

GetAvailableTimes() → ndarray

Returns the available times at which data can be read

Returns:

available times at which data can be read

Return type:

np.ndarray

GetModel()

Function to recover the dpf Model associated to the rst file

Raises:

RuntimeError – if the fileName is not already set

Returns:

dpf model

Return type:

Model

GetPostResults(post_names=[], locations=[])

MeshRead() → Mesh

Function that performs the reading of a mesh in a rst file

Returns:

mesh containing reading result

Return type:

Mesh

Read(time: float64 = None, timeIndex: int64 = None, fromElementalNodalToNodal=True) → Mesh

Function that performs the reading of the mesh and the fields in the rst

Parameters:

• time (float, optional) – time at which the field is read, by default None

• timeIndex (int, optional) – time index at which the field is read, by default None

Returns:

output Mesh object containing the results

Return type:

Mesh

ReadField(fieldname, time: float64 = None, timeIndex: int64 = None, fromElementalNodalToNodal=True) → ndarray

Function that performs the reading of a field

Parameters:

• fieldname (str, optional) – name of the field to be read, by default None

• time (float, optional) – time at which the field is read, by default None

• timeIndex (int, optional) – time index at which the field is read, by default None

Returns:

for an ElementalNodal field:

if fromElementalNodalToNodal = True (default), this function returns a numpy array of the averaged value at the nodes if fromElementalNodalToNodal = False, this function returns a list of discontinuous FEfields (one for each component of the field)

Return type:

np.ndarray

ReadMetaData()

Function that performs the reading of the metadata of an rst file (number of points, number of elements, timesteps, fields)

Reset()

Resets the reader

SetFileName(fileName: str) → None

Parameters:

fileName (str) – path to the simulation

SetTimeToRead(time: float64 = None, timeIndex: int64 = None) → int64

Sets the time at which the data is read

Parameters:

• time (float, optional) – time at which the data is read, by default None

• timeIndex (int, optional) – time index at which the data is read, by default None

Returns:

time index at which the data is read

Return type:

int
