Solver:
Piezoelectric materials in static 3D
Quadratic 2D electrostatic elements
Stiffness and compliance matrix material types
Permittivity matrix material type
Bonded contact includes shell edges and beam/truss ends and edges
Gyroscopic loads with two rotation axes in static 3D analysis
Tension only truss elements in static 3D and Nonlinear static 3D
Frictionless support on the edges of beam and truss elements
Non-zero initial temperatures on bonded contact nodes
More accurate calculation of temperature dependent specific heat
Tools:
Automesh 2D works on any plane
Quad local refinement work with quad8 elements
Save some features to ANSYS command file
Opening a .vol file shows the surfaces as named selections
Display/interface:
Paint selection of faces with an angle tolerance to detect edges
Cutting plane slider works for geometry view to help select internal features
Internal mesh edges don't show through the surfaces as much as before
Node dot size automatically scales in proportion to the mesh
F2 key to rename renameable items in the outline tree
+/- keys for zooming
Arrow keys move the timeline slider by single time steps
Status bar shows the number of selected items
Option to swap the mouse buttons for pan and rotate
Improved support for high DPI screens
Deformed view in one click
Nonlinear thermal solver shows convergence graph
Blank element surfaces without contour plot are available in the solution
CalculiX interoperability:
Selectable working directory for CalculiX's files
Component definitions are transferred to the postprocessor
Tables are retained between solves
Laminate (composite) materials on Quad8 elements. Doesn't transfer component definitions with them.
Plastic materials: Bilinear hardening and Ramberg-Osgood
Hyperelastic materials: Ogden, Mooney-Rivlin, and Neo Hooke
Temperature dependent thermal conductivity and specific heat
Thermal stress with isotropic thermal expansion coefficients
More robust with several failure modes corrected
Force loads on offset shell faces no longer include moment loads due to the offset. CCX adds them itself.
Linux:
Improved compatibility with Wine on Linux. Recognizes product keys and doesn't pop up error messages on graphs
Removed:
Relaxation factor for thermal and Navier-Stokes analysis types

Hope I am not the problem creator.

I suspect it is something to do with administrator priviliges, which I normally need to confirm if I want to save something in the c:/Program Files.

About the arrow keys for moving between increments of nolineal analysis, as they work also for pan the model in the view, maybe could be better to add an specific shortcut (shift + arrows keys?)
For the lab option for reduced integration element, can be moved to something in the model file and not in the program? Is very easy to forget activated between sessions and finishing making standard analisis with reduced elements. Maybe a warning in case of launching a lineal analysis having that activated.
On CCX nolineal imported results, can be limited the scale of the timeline to the real computed increments and not the desired number? Guess that V4 work like that, now is a little confusing to have the cursor over noncomputed increments
I have found that if I select Components in the results tree (CCX imported), I can have a visualization of the deformated model without results (every component whit his own mesh color). Can be removed the scale of colors then in this visualization mode?
For all the rest... amazing job :-)

For "Use the same directory as LIML file", i'll try to clarify that and the error message. Most people should leave it turned off.
For angles, I hope to avoid having to enter numbers. You can zoom in and out to change the size of the region it includes.
The arrow keys follow the common Windows convention of acting on the control that has focus. This is to help usability because it's familiar.
Labs options are just quick hacks so you have to take care with them. When/if I find out a suitable place to put it, it'll become a proper persistent setting saved with the model.
For the time line, I agree it's misleading. Hopefully I'll get that improved for a future version but not this one.
Color scale - good idea.

In my view, adaptive refinement has a higher priority than topology optimization. So that's way down the track.
Thanks
Yes, automatically remeshing areas with more error/etc. Not to say I'll get there any time soon but I think that's more useful than, and perhaps a necessary part of, topology optimization.
Any suggestions welcome!

The main problem is D1 is too big. In this case it should be 3e-9 m^2/N (=1/(332MPa) ). I'll try to clarify what that means in the program and perhaps include 1/MPa because different people use different definitions for their (in)compressibility constants. Thanks for pointing out this confusing aspect.
When parts pass through each other like that, it can mean the pressure-overclosure slope is too small. Unfortunately this is a tricky parameter that you need a bit of trial and error to tune. I found 100 000 Pa/mm works better but it somehow explodes near the end of the time steps.
Thanks,
