Hi,
Is there a capability to construct beam-column elements while specifying moment releases at one of the nodes (no rotational stiffness). If so, what is the interpreter argument to specify that.
Best,
Mohamed

Compiling the current version of OpenSees
I just updated my OpenSees using CVS. I used to have an OpenSees that was compiling wonderfully on VC++6.0. Now, I ran into a ubiquitous compile-tine error. The compiler did not understand (and neither did I), the lines containing "<<<<<<<<<<SomeNunmber", or "=========SomeClassName&qu...

Error Message
Hi, While running an analysis using newly-developed classes, I get the error message " WARNING SuperLU::solve(void)- Error -1 returned in factorization dgstrf()". I checked the source code and found that this error is in the file SuperLU.cpp but failed to understand the condition which lau...

TclXXFiberSectionCommand.cpp
I have written a XXFiberSection2d class [XX is a dummy] which is a modification on the existing one. The class is up and running. My question has to do with considerations of good coding. It is recommended practice that - instead of adding the required interpreter command in the original TclModel Bu...

Previous versions of OS
I seem to recall there used to be an option to download previous (compiled) versions of OpenSees. Is this discontinued as a policy or can I just not find it anymore? I am looking for OS versions 1.5 or older (roughly a year and a half ago).

Comiler Link Warning
I get the following at trying to link OpesSees with new materials implemented. It compiles and runs but I am afraid it might be producing garbage. I searched it online but the little I found didn't help. Any more well-versed C++ developers can come to the rescue? LINK : warning LNK4075: ignoring /IN...

I have to say first that I am thankful for this discussion. It has been very useful to learn about the MinMax material. I will need to use is shortly and I had been resorting to an ungraceful manipulation of hysteretic-trilinear instead. As for the section analysis continuing after the farthermost f...

Trying to remove nodes
Hello, I have a 2D propped cantilever model. Nothing fancy - two orthogonal beanWithHinge elements set up between 3 nodes. Two nodes are constrained in all DOF and one is free. Within the analysis, I try to use remove element; remove node; remove loadPattern to simulate element loss. The program cra...

Coding Style
This question I should have sent by personal email but I thought that putting it here will lend its answers to the eyes of other "newbie" developers like myself who have similar concerns - namely designing their own classes so that when time comes it will not be a big problem to integrate ...

Yes!!! Docuemtation again. I ran into at least one occasion where I wanted to use this model (which you can only know of if you happened to be writing your own code in OpenSees for something else - or kept a close eye on the discussion forum) but couldn't because of lack of it. Not only is there no ...

"Possible" Bug with the FiberSection3D?!!
Hey, I am set to work on a modified - confined concrete - fiber section starting from the existing one. In exploring the existing code I ran into the following method: FiberSection3d::addFiber { and near the end it recomputes the centroid by // Recompute centroid for (i = 0; i < numFibers; i++) { yL...

Help Needed with Material Model Arguments
I am trying to use Steel02, and Concrete02 materials. Does anybody now what typical value to use for the "unloading stiffness ratio" for concrete. More importantly, any idea how the isotropic hardening model variables works? To be more speciific: :!: Let's consider similar hardening in com...
