VIEW OPTIONS DEFORM Component [Factor]

        

FEMVIEW Command only.

This command enables the user to present analysis results on a view of the deformed model. The deformed model view is produced by adding a specified component of results, or component resultant, to the nodal point co-ordinates. A scale factor to be applied may be specified, but if no scale factor is specified then a factor is calculated such that the model is deformed so that the maximum nodal deformation will be 10mm (if viewed normal to the screen).

Where the user has a results attribute named 'DISPLACE' with vector components `X', `Y', `Z' and `ALL' then a shortened form of the command is available to apply these components.

Alternatively, it is possible to deform the mesh using the vector components of any attribute of nodal materially independent results.

Component Comments

X Component `X' of attribute `DISPLACE' is chosen.

Y Component `Y' of attribute `DISPLACE' is chosen.

Z Component `Z' of attribute `DISPLACE' is chosen.

ALL The resultant of the components of attribute `DISPLACE' is chosen.

USING Attribute Name A component of any nodal attribute that is a vector quantity may be chosen.

OFF Return to undeformed view.

Factor = A new scale factor may be applied to the currently chosen attribute. The displayed 'factor' should be used as a guide to the value.

Notes:

1.

Effect of loadcase selection
A loadcase containing the requested attribute and component must be current when the VIEW OPTIONS DEFORM command is issued. The selection of a new loadcase will cancel the VIEW OPTIONS DEFORM command if the required attribute and component do not exist in the new loadcase.

2.

A factor of -1
A factor of -1 is used internally to FEMVIEW to reset the scale factor to the default value. Where a scale factor of -1 is required the user should set the scale factor to -1.01 or similar.

Examples:

1.

VIEW OPTIONS DEFORM X

The component `X' from the attribute `DISPLACE' is used to deformed the mesh.

2.

VIEW OPTIONS DEFORM ALL 5.0

The resultant of the `X', `Y' and `Z' components of attribute `DISPLACE' is used to deform the mesh. A scale factor of 5.0 is applied.

3.

VIEW OPTIONS DEFORM USING EIGEN YDIRECT 4.3

The component `YDIRECT' of attribute `EIGEN', where this is a vector quantity, is used to deform the mesh. A scale factor of 4.3 is applied.

4.

VIEW OPTIONS DEFORM 70.0

A scale factor of 70.0 is applied to the currently deformed mesh. If the mesh is not currently deformed then no scaling will take place.

5.

VIEW OPTIONS DEFORM OFF

The deformed mesh is turned off and the undeformed view is redrawn.
