I have two sets of output from a finite element program that I want to
display, but as opendx doesn't handle non-linear interpolations in
cells, they are of different grids. The first output is displacements,
which has the same cells in the finite element program and opendx. The
second set of data is based on the division of the finite element cell
into a composite cell containing 12 different cells, as given below:
_______
|\__|__/|
| | | | |
---------
| |_|_| |
|/__|__\|
(sorry about the ascii art...)
This gives me an approximation to the higher order interpolation, as it
includes more points within the cell. The cell used for the
displacements and the composite cell contain the same vertices. I want
to show how the grid is deformed. Is there a way to that allows me to
interpolate the displacement values of the composite cell inside dx?
ie. I want the vertices used in the composite cell to be:
vertex_undeformed + displacement (shows displacement of grid)
and the vertices for all the cells contained in the composite cell to be
a linear interpolation of these displacements.
Can I do this within dx? Or will I have to do this in my finite element
code itself?
Thanks,
