This method is used to adjust the midside node of second-order elements of an orphan mesh part.

Note

Parameters:¶

cornerNodes¶: A sequence of Node objects specifying the nodes towards which connected midside nodes will be biased.
parameter¶: A Float specifying the normalized distance along the edge of the midside nodes. Possible values are 0.0 ≤ parameter ≤ 1.0, where 0.0 specifies the position of the corner node. The default value is 0.5.

cleanMesh( mergeTolerance, growEdges=0, elements='', refEdge='', thicknessDir=None, moveLayers=False, )[source]¶

Note

Check MeshEditPart.cleanMesh on help.3ds.com/2017.

Parameters:¶

mergeTolerance¶: A Float specifying the edge length tolerance. During the operation, edges shorter than the given tolerance will be collapsed, or grown to the specified length.
growEdges=0¶: A Boolean specifying whether short element edges will be grown to the specified tolerance. Default is False, meaning short edges will be collapsed.

refEdge=''¶: A MeshEdge specifying a reference edge to indicate a topological direction in a structured mesh that will limit which edges within the element domain are considered. That is, only edges that are found to be topologically parallel to the given reference edge will be considered by the operation. By default all edges of the element domain are considered, unless thicknessDir is specified, in which case the operation will attempt to determine the topological edges from the thickness direction.
thicknessDir=None¶: A tuple of two or three Floats indicating a vector along which element edge lengths will be measured.
moveLayers=False¶: A Boolean indicating whether element edges will be all grown in the direction of the thickness vector specified by thicknessDir. This argument is ignored unless growEdges is True and thicknessDir is provided. When this argument is True the growth of any given element edge will no longer be constrained by short edges on neighboring elements, but elements could move from their original positions in cases where there are multiple adjacent layers of thin elements. The default value is False.

Other Classes¶

class MeshEditOptions[source]¶

Bases: object

The MeshEditOptions object stores settings that specify the behavior when editing meshes on parts or part instances. The MeshEditOptions object has no constructor. Abaqus creates the MeshEditOptions member when a session is started.

Note

This object can be accessed by:

mdb.meshEditOptions

Note

Check MeshEditOptions on help.3ds.com/2017.

Member Details:

setValues(maxUndoCacheElements=0, enableUndo=0, _suspendUndo=0)[source]¶

This method modifies the MeshEditOptions object.

Note

Check MeshEditOptions.setValues on help.3ds.com/2017.

Parameters:¶

maxUndoCacheElements=0¶: A Float specifying the maximum allowable mesh edit undo cache size in millions of elements. If this value is set to at least the number of elements on a given part or part instance, at least one level of undo/redo capability is assured for subsequent mesh edit operations on that part or part instance. The default value is 0.0.
enableUndo=0¶: A Boolean specifying whether undo/redo of mesh edit operations will be enabled. If enableUndo =OFF any existing cache for undo/redo operations will be cleared for all parts and assemblies in all models. The default value is OFF.
_suspendUndo=0¶: A Boolean specifying the suspension of undo/redo for mesh edit operations. When undo/redo is suspended, undo/redo will not be available after subsequent mesh edit operations on a given part or part instances. Any pre-existing cache for mesh edit operations on other parts or assemblies in any model will be unaffected. The default value is OFF.If you change the value of enableUndo to True, Abaqus sets _suspendUndo to False.
