Extracts scalar values from vector or tensor values.
Inputs
|
src: a value table.
component: x,y,z,mag,xx,yy,zz,xy,yz,zx,p1,p2,p3,vm.
|
Outputs
|
answer: a value table.
|
Notes
|
| • | src must be a vector or tensor format, and answer must be scalar format. |
| • | If src is a constant value table (created by the Constant operator), no records will be added to the answer table. |
| • | Valid components for vectors are “X, Y, Z, Mag” |
| • | Valid component strings for tensors are “XX, YY, ZZ, XY, YZ, ZX, P1, P2, P3, or VM”. |

Expression Builder
|
In the Expression Builder, the ScalarExtract operator is called when a scalar or vector table is followed by a period, then by the component.
For example:
displacement.x: extracts the x-component of the displacement vector.
stress.vm: extracts the vonMises from the stress tensor.
stress.yy: extracts the normal y component from the stress tensor.
