The Math library contains the following Tensor operators:
Stores the deviatoric part of src into answer.
Inputs
|
src: a tensor value table.
|
Outputs
|
answer: a tensor value table.
|
Notes
|
| • | src and answer must be tensor format. |
| • | If src is a constant value table (created by the Constant operator), no records will be added to the answer table. |
|
Expression Builder
|
dev(src)
|
XML Example
|
<call name="DeviatorT" src="src_tab"
answer="ans_tab" />
|
|
Stores the spherical part of src into answer.
Inputs
|
src: a tensor value table.
|
Outputs
|
answer: a tensor value table.
|
Notes
|
| • | src and answer must be tensor format. |
| • | If src is a constant value table (created by the Constant operator), no records will be added to the answer table. |
|
Expression Builder
|
sph(src)
|
XML Example
|
<call name="SphericalT" src="src_tab"
answer="ans_tab" />
|
|
Stores one of the principal axes of the src tensor into answer.
Inputs
|
src: a real tensor value table.
axis: a string "major", "mid", or "minor" (default = "major").
|
Outputs
|
answer: a real vector value table.
|
Notes
|
| • | src and answer must be bound to the same entity type. |
| • | If src is a constant value table (created by the Constant operator), no records will be added to the answer table. |
|
Expression Builder
|
PrincipalAxisVector(src,"Minor")
|
XML Example
|
<call name="PrincipalAxisVector" src="src_tab"
axis="minor" answer="ans_tab" />
|
|
Creates a 3-D tensor from six scalar tables and stores the result in answer.
Inputs
|
xx: a scalar value table.
yy: a scalar value table.
zz: a scalar value table.
xy: a scalar value table.
yz: a scalar value table.
zx: a scalar value table.
sysid: a system ID or keyword (default = 0).
|
Outputs
|
answer: a tensor value table.
|
Notes
|
| • | xx, yy, zz, xy, yz, zx and answer must be real bound to the same entity type, and of the same domain (complex or real). |
| • | sysid is a string containing an ID or keyword that defines the system the tensor will be created relative to: |
| o | “0”: Global (the default) |
| o | A positive integer: a system ID in the model |
| o | “elem”: the elemental coordinate system |
| o | “anal”: the nodal analysis system |
| o | “ply”: the elemental ply system |
| o | “mat”: the elemental material system |
| • | If xx is a constant value table (created by the Constant operator), no records will be added to the answer table. |
| • | If a record cannot be found in all six input scalar tables, no tensor will be created. |
