<DIV><FONT size=2 face=Arial>You might like to consider creating separate
unstructured grids for your elements depending on their visual display
characteristics. For example, a mass element could be shown as a sphere with
diameter proportional to the mass. Actors for each sub grid can then be added to
a prop collection or assembly. You can also make each grid share the same points
and point data even though they will be "oversize" for the sub grids.
However, this does lead to greater programming complexity.</FONT></DIV>
<DIV><FONT size=2 face=Arial></FONT> </DIV>
<DIV><FONT size=2 face=Arial>If any of your point data is discontinuous, for
example, stress components between dissimilar materials, you should ponder this
problem at an early stage.</FONT></DIV>

<P class=MsoNormal><SPAN lang=EN-US>Our finite-element application has
‘interface elements’ which are used to model discontinuities between
‘conventional’ elements. We would like to be able to visualize these as
transparent elements with one or more lines connecting the sides of the
interface element. For this we need to filter such elements and process them
in a proper way. What would the preferred way of discriminating between
interface and conventional elements be? Should we add a boolean attribute to
each cell specifying whether it is an interface element?<O:P></O:P></SPAN></P>
