** Changes to FElt from 3.05 to 3.06 (released 3/24/00)
|
|
|
|
The following bugs/things were fixed/changed:
|
|
1. the details stream was getting set all the time on the regular
|
|
writing of structural results, producing extraneous output
|
|
if the details flag hadn't actually been set
|
|
2. the text output for static thermal analysis was going to
|
|
stdout rather than the output window in velvet
|
|
3. as part of the rearrangement of the isoparametric elements and
|
|
element stresses/nodally averaged stresses, the components of the
|
|
stress vectors for cst, iso_2d, iso_quad, and axisymm elements
|
|
have changed. All of them (plus bricks) now have 10 components:
|
|
sigma_x, sigma_y, sigma_z, tau_xy, tau_xz, tau_yz, sigma_1, sigma_2,
|
|
sigma_3, and the von Mises stress. (sigma_r, sigma_z, sigma_theta,
|
|
tau_rz, 0, 0, sigma_1. sigma_2, 0, sigma_VM for axisymm elements).
|
|
|
|
The following features were added:
|
|
1. all of velvet's post-processing graphics except animation and mode
|
|
shapes have been ported over to OpenGL. The big reason for this is to
|
|
provide 3D color plots of stress and displacement for problems
|
|
using brick elements, but it also makes the post-processing code
|
|
quite a bit cleaner and provides nice rotation control. Try
|
|
loading the new examples brick_cap.flt and brick_ring.flt into
|
|
velvet (ignore the no nodes in the z=0 plane message), solve,
|
|
and plot stresses or displacements. As mentioned above, all of
|
|
the plottable stresses are now nodally averaged results. The
|
|
component can vary from 1 to 10. Displacements are treated the
|
|
same as before. Saves don't really work yet. If you need a
|
|
dump you can always xwd the window on your own and crop it and
|
|
convert it as necessary.
