[GoogleCodeExporter]

What steps will reproduce the problem?
1. Run the attached file.

What is the expected output? What do you see instead?
Crashes after 15.735s showing in the terminal with
"ldy.c: 733, Unhandled error: Eigen decomposition of a diagonal W block failed"

What version of the product are you using? On what operating system?
0.596 Beta Win XP 32-bit executable

Please provide any additional information below.
I can't open the database with the viewer (throws "pbf.c: 248, Unhandled error:

Have re-run up to 12.0 seconds, runs fine, model configuration is fine.

File attached above is not correct (doesn't pick up the boundary conditions), 
and may not have been the analysis which generated the above error.

I suggest you park this issue for the moment, if I can reproduce it I'll add a 
comment/upload correct files.

Would be good to have the file so to catch the reason for this bug (must be 
ill-conditioned contact detection).

On the other hand, from the error message I can see that I can do something 
about this sort of situation, rather than just stop the simulation. I could 
simply ignore contact points that generate this sort of issue. That's another 
way to "solve" this:)

Let's keep this open for now.
