Vector Commands
The Vector Column contains calculator operations which can only be performed on vector stack entries. Drop-down menus in this column are Scal? (convert vector to scalar) and Unit Vec (create unit vector). Standard vector algebra operations (Dot, Cross, etc.) are also present.
Use these commands to perform operations on vector quantities.
|
Replaces the vector in the top register with a scalar quantity whose value is a component of the vector, your choice of ScalarX, Scalar Y, or ScalarZ. |
|
|
Multiplies or divides the vector field quantity in the top register by a material property, or if you select MassDensity as the material property, produces a scalar that operates like a named variable. |
|
|
Takes the magnitude of the vector quantity in the top register. The magnitude of a complex vector is defined to be the length of the real vector resulting from taking the modulus of each component of the original complex vector. |
|
|
Takes the dot product of the vector quantities in the top two registers. |
|
|
Takes the cross product of the vector quantities in the top two registers. |
|
|
Takes the divergence of the vector quantity in the top register. |
|
|
Takes the curl of the vector quantity in the top register. |
|
|
Computes the tangential component of a vector quantity along a line |
|
|
Computes the normal component of a vector quantity on a surface such as a cutplane or object surface. |
|
|
Computes the normal or tangent unit vector. The unit vector is a "wild card" entry. The context is specified at the time of plotting, integrating, or report generation. The drop-down lets you select from Tangent, Normal, or CoordSys[X, or Y, or Z] |
|
| X Form | Transforms to your choice of Cylindrical or Spherical. |
