BasicTools.FE.KR.KRFromDistribution module

BasicTools.FE.KR.KRFromDistribution.CheckIntegrity(GUI=False)[source]
class BasicTools.FE.KR.KRFromDistribution.KRFromDistribution[source]

Bases: KRBase

Class to impose values in the primary unknown of the system for the moment this only work with iso-parametric fields

FixUsingFEFields(inputFEFields: List[FEField]) KRFromDistribution[source]

Set the fields to be used to impose the dof values

Parameters:

inputFEFields (List[FEField]) – a list of FEField (the order is not important)

Returns:

self

Return type:

KRFromDistribution

FixUsingNodeFields(mesh: UnstructuredMesh, nodalField: Dict[str, ArrayLike]) KRFromDistribution[source]

Set the fields to be used to impose the dof values. Internally we convert the numpy array into fields with the function : BasicTools.FE.Fields.FieldTools.NodeFieldToFEField()

Parameters:
  • mesh (UnstructuredMesh) – the mesh

  • nodalField (Dict[str,ArrayLike]) – a dict with key:value in the form of “u”:numpy(3,NbNodes)

Returns:

self

Return type:

KRFromDistribution

GenerateEquations(mesh: UnstructuredMesh, fields: List[FEField], CH: ConstraintsHolder | None = None, solutionFields: List[FEField] | None = None, reactionFields: List[FEField] | None = None) ConstraintsHolder[source]

Generate the equation to impose the constraints defined by this class. More information about this

Parameters:
  • mesh (UnstructuredMesh) – The mesh

  • fields (List[FEField]) – The list of fields to be used to compute the numbering (in the order on the linear system to be solved)

  • CH (Optional[ConstraintsHolder], optional) – the ConstraintsHolder to store the equations, if None is provided a new object is created, by default None

  • solutionFields (Optional[List[FEField]], optional) – In the case of an iterative solver (i.e. in a newton loop) the current solution, by default None

  • reactionFields (Optional[List[FEField]], optional) – The user can provide the reactions fields ( the integral of the internal forces), by default None

Returns:

the ConstraintsHolder with the new equations

Return type:

ConstraintsHolder

Raises:
  • RuntimeError – if no data is provided. the user must call FixUsingFEFields or FixUsingNodeField to provide the fields

  • LookupError – If the user impose a restriction on a field (using .AddArg()) but not available on the problem
