Speed Improvements
I am noticing significant speed improvement between versions 2.1.0 and 2.2.0.
For a model with 1660 nodes and 2225 elements:
OpenSees 2.1.0: 91 sec
OpenSees 2.2.0: 39 sec
Obviously this is only one data point, but that is an incredible improvement.
I thought that the speed-up was suspicious, but I have verified the output is identical (within reason).
I am curious to what parts were optimized. I suspect that my model is an extreme example.
Thanks,
Dan

@dborello: What type of analysis are you performing? Could you describe what were your analysis options including the system of equations setup etc.?
Thanks

Re: Speed Improvements
Arbarbosa,
My model is utilizing the Steel02 material model (for the most part) and has the 540 truss and zero-length elements and 100 nonlinear beam columns.
My analysis parameters are:
constraints Plain
numberer RCM
system ProfileSPD
test EnergyIncr 1.0e-8 30 1
algorithm NewtonLineSearch 0.5
analysis Static
integrator DisplacementControl 769 1 6.250000e-002
analyze 472
I hope this helps,
Dan

Version 2 2 0 released
I am switching to using version 4 and I am trying to access my version 3 templates through version 4. If I just copy them to the templates folder in version 4 then they do not load properly. How can I import the version 3 templates I created in the my templates/version 3 area?
Thanks, Kirsten
