60.15 OdbDatumCsys object

The OdbDatumCsys object contains a coordinate system that can be stored in an output database. You can create the datum coordinate system in the Visualization module during an Abaqus/CAE session and save the datum coordinate system to the output database before you exit Abaqus/CAE. Alternatively, the analysis code can write the datum coordinate system to the output database.

60.15.1 DatumCsysByThreePoints(...)

This method creates an OdbDatumCsys object using three points. A datum coordinate system created with this method results in a fixed system.

Path

odb.rootAssembly().DatumCsysByThreePoints

Prototype

odb_DatumCsys&
DatumCsysByThreePoints(const odb_String& name,
                odb_Enum::odb_DatumCsysTypeEnum coordSysType,
                const odb_SequenceFloat& origin,
                const odb_SequenceFloat& point1,
                const odb_SequenceFloat& point2);

Required arguments

name

An odb_String specifying the repository key.

coordSysType

An odb_Enum::odb_DatumCsysTypeEnum specifying the type of coordinate system. Possible values are odb_Enum::CARTESIAN, odb_Enum::CYLINDRICAL, and odb_Enum::SPHERICAL.

origin

An odb_SequenceFloat specifying the coordinates of the origin of the datum coordinate system.

point1

An odb_SequenceFloat specifying the coordinates of a point on the local 1- or -axis.

point2

An odb_SequenceFloat specifying the coordinates of a point in the 1–2 or – plane.

Optional arguments

None.

Return value

An OdbDatumCsys object.

Exceptions

None.

60.15.2 DatumCsysByThreeNodes(...)

This method creates an OdbDatumCsys object using the coordinates of three OdbMeshNode objects. A datum coordinate system created with this method results in a system that follows the position of the three nodes. Results, such as those for displacement, are resolved into the orientation of the datum coordinate system without regard to the position of its origin. The last three arguments are given in the form of an OdbMeshNode object.

Path

odb.rootAssembly().DatumCsysByThreeNodes

Prototype

odb_DatumCsys&
DatumCsysByThreeNodes(const odb_String& name,
                odb_Enum::odb_DatumCsysTypeEnum coordSysType,
                const odb_Node& origin,
                const odb_Node& point1,
                const odb_Node& point2);

Required arguments

name

An odb_String specifying the repository key.

coordSysType

An odb_Enum::odb_DatumCsysTypeEnum specifying the type of coordinate system. Possible values are odb_Enum::CARTESIAN, odb_Enum::CYLINDRICAL, and odb_Enum::SPHERICAL.

origin

An OdbMeshNode object specifying a node at the origin of the datum coordinate system.

point1

An OdbMeshNode object specifying a node on the local 1- or -axis.

point2

An OdbMeshNode object specifying a node in the 1–2 or – plane.

Optional arguments

None.

Return value

An OdbDatumCsys object.

Exceptions

None.

60.15.3 DatumCsys(...)

This method copies oneOdbDatumCsys object to a new OdbDatumCsys object.

Path

odb.rootAssembly().DatumCsys

Prototype

odb_DatumCsys&
DatumCsys(const odb_String& name,
          const odb_DatumCsys& datumCsys);

Required arguments

name

An odb_String specifying the repository key.

datumCsys

An OdbDatumCsys object specifying the object to be copied.

Optional arguments

None.

Return value

An OdbDatumCsys object.

Exceptions

None.
