Deformation

) to deform the plot according to a vector quantity — for example, the displacement field in structural mechanics. You can add a deformation to most 2D and 3D plots: annotation, arrow, contour, isosurface, line, slice, streamline, surface, and volume plots. By default, COMSOL Multiphysics scales the deformation to 10% of the geometry.


	The default scaling often uses a scale factor that is much larger than 1, which means that plotted deformation is exaggerated to clearly show the deformed shape. Use a scale factor of 1 to plot the actual deformation in a structural mechanics simulation, for example.

In the , add and define a or . Right-click the plot node (for example, ) and select .

Scale

Select the check box to edit the default value for the scale factor.


	Using a scale factor of 1 and equidistant displacements in the x, y, or z direction, you can plot several instances of the geometry side by side to, for example, visualize the solution at some times, for some parameter values, or to illustrate multiple eigenmodes. In such a plot, you would typically specify the dataset in each plot individually and turn off the color legends and titles for each separate plot.

Advanced

To control the automatic scaling of the deformation, you can change the value in the field from the default 0.1 (that is, 10% of the geometry) to another scalar, positive value. If you use a manual scale factor in the section above, the maximum relative deformation setting is not applicable.
