I'm not sure what type of problem you are trying to solve, but this may also happen if you are writing a lot of information to the hard disk. If that is the case, try turning off your recorders and check to see if you get an improvement. Parallel version is being cleaned up and will be uploaded to C...

I can't see why we can't have a recorder that will return the time of occurence of the maximum. This will be extremely useful for other things too.

You may want to consider using 3 elements instead of one, especially if the member steps in size (not tapered). If your element is tapered, you need to figure out the number of integration points that give you reasonable integration point "weights". You still may want to consider multiple ...

There are advantages and disadvantages. Advantages: Open source, Open Architecture, FREE!, Specialized element and material models (like fiber beam-column element), parallel (yet to become usable), easy to add your element and material models (even solvers etc...), C++ Object Oriented design, Reliab...

This is indeed a good suggestion, and it is something that I had on my mind for while. The distinction in my view is "scripting" vs "model state". The model definition may be changing during an anlysis by adding/removing elements, materials, and it would be useful to be able to e...

The fact that the release version is not crashing does not mean there's no problem! You are most likely writing some data beyond the end of an array. Theoretically, the behavior of your program is unpredictable (but it might just work!). Under Debug mode, array boundary checks will generate the exce...

Frank,

Can you please comment on the possibility of running Opensees in parallel mode on a cluster of Windows machines?
My understanding is that parallel processing is currently limited to Unix/Linux.

Thanks,
