MaterialOrientation(...)

This method creates a MaterialOrientation object.

Path

mdb.models[name].parts[name].MaterialOrientation

Required arguments

None.

Optional arguments

region: A Set object specifying a region for which the material orientation is defined.
localCsys: A DatumCsys object specifying the local coordinate system or None, describing the material orientation for the given region. In the ODB, this member was previously accessible using "csys," but support has now been added for localCsys and the csys member will be deprecated.
axis: A SymbolicConstant specifying the axis of a datum coordinate system about which an additional rotation is applied. For shells this axis is also the shell normal. Possible values are AXIS_1, AXIS_2, and AXIS_3. The default value is AXIS_1.
angle: A Float specifying the angle of the additional rotation (if accessed from the ODB instead of the MDB, it will be a string instead of a float). The default value is 0.0.
stackDirection: A SymbolicConstant specifying the stack or thickness direction. Possible values are STACK_1, STACK_2, STACK_3, and STACK_ORIENTATION. The default value is STACK_3.
fieldName: A String specifying the name of the DiscreteField object specifying the orientation. The default value is an empty string.
orientationType: A SymbolicConstant specifying the method used to define the material orientation. If orientationType=SYSTEM, the region and localCsys arguments are required. If orientationType=FIELD, the fieldName argument is required. Possible values are GLOBAL, SYSTEM, FIELD, DISCRETE, and USER. The default value is GLOBAL.
normalAxisDirection: A SymbolicConstant specifying the axis that is defined by the normal axis direction for a discrete orientation. Possible values are AXIS_1, AXIS_2, and AXIS_3. The default value is AXIS_3.
normalAxisDefinition: A SymbolicConstant specifying the method used to define the normal axis direction for a discrete orientation. Possible values are SURFACE, NORMAL_DATUM, and NORMAL_VECTOR. The default value is NORMAL_VECTOR.
normalAxisRegion: A Surface object specifying a region whose geometric normals define the normal axis for the discrete orientation.
normalAxisDatum: A DatumAxis object specifying the Datum Axis or None, describing the normal axis direction for the discrete orientation.
flipNormalDirection: A Boolean specifying the flag to reverse the direction of the defined normal axis direction. The default value is OFF.
normalAxisVector: A sequence of Floats specifying the vector that defines the direction of the normal axis of the discrete orientation.
primaryAxisDirection: A SymbolicConstant specifying the axis that is defined by the primary axis direction for a discrete orientation. Possible values are AXIS_1, AXIS_2, and AXIS_3. The default value is AXIS_1.
primaryAxisDefinition: A SymbolicConstant specifying the method used to define the primary axis direction for a discrete orientation. Possible values are SURFACE, PRIMARY_DATUM, and PRIMARY_VECTOR. The default value is PRIMARY_VECTOR.
primaryAxisRegion: A Set object specifying a region whose geometric tangents define the primary axis for the discrete orientation.
primaryAxisDatum: A DatumAxis object specifying the Datum Axis or None, describing the primary axis direction for the discrete orientation.
flipPrimaryDirection: A Boolean specifying the flag to reverse the direction of the defined primary axis direction. The default value is OFF.
primaryAxisVector: A sequence of Floats specifying the vector that defines the direction of the primary axis of the discrete orientation.

Return value

A MaterialOrientation object.

Exceptions

None.
