RESULTS INVARIANT Attribute [Component] [Complex_part]

                    

This command is used to specify the element invariant attribute and component of analysis results required for assessment. The names of the attributes and components will be user-defined, and these will be offered in the form of a menu in a similar way to the standard commands available in FEMVIEW..

Invariant results in FEMVIEW are sets of results submitted as constant for the element, although different values may be submitted for each surface. The results will be presented at the centroid of the element.

For selection of the required surface see also the RESULTS RANGE command. If no surface is specified, and results are available at more than one surface, the default condition is that values for the first surface will be selected.

For components which are complex an optional function can be specified by the user to produce a real value that can be presented. If the complex number is represented by x + iy the functions that can be applied are:

Complex_part Comments Equation used

REAL Produces the real component of the complex x number. (This is the default if no function is specified)

IMAGINARY Produces the complex component of the y complex number.

$$\theta x\cos\theta + y\sin\theta$$ Resolves the complex number at a given

$$\theta \theta$$

$$\sqrt{x^{2}+y^{2}}$$ MAGNITUDE Produces the magnitude of the complex number.

$$\tan ^{-1}(y/x)$$ PHASE Calculates the phase angle of the complex number. The angle returned is in the range

$$\pm 180$$

Notes:

1.

It is possible to define results that have no `Component' names; for example, Von Mises stress.
