The OpenSees Community

dear fmk thank you so much for quick and brilliant response of yours this meant a lot for me thanks for your precoius time, and off course i will review my text books about finite element.

Dear fmk, I'm modeling a simple 1 story wall using every possible element in OpenSees( ShellMITC4,quad,spsbrick,stdbrick,...) and using it correctly like verification example "PlanarShearWall" but results are so different from Sap2000(I couldn't reproduce answers you assign to sap results in "Planar...

Dear johnnyontheweb, well with all the respect for dear fmk, but I couldn't build opensees by tcl 64 bit!!!! actually it's kinda ridiculous I completely removed X64 tcl and installed x86 tcl and magical! it worked! hear is complete instruction: 1.download rev5641 2.install X86 version of tcl (no mat...

Dear all,
thank you so much for your help

Dear fmk, thank you so much for quick response, actually I knew that OpenSees do the P-large delta but I was seeking a way to do both P-Delta & P-delta by only one element (not by breaking it up into some elements) and you just showed me a way in 2D thanks! by the way would you please give me OpenSe...

dear nazgol,
did you solve this issue? I'm dealing with it now, I need help please...I checked last revision(5634) but I get same results as you did !

Dear Bag006, Off course I gave it a try and numerous LNK2019 error showed up from VS and I changed my windows to 32bit platform and all of errors vanished and everything now works fine in 32bit windows but I'm sick of 32bit windows so I wondered if anyone did the compiling and building on 64bit wind...

Dear all,
can anyone compile and build opensees on x64 platform without any link error?
If yes, would you please explain steps for me please?

dear brag006 I've followd your posts in forum and I guess you got the main picture of opensees can I ask you a few questions about it? I'm sorry for asking this here but I really need help for my thesis, here is my e-mail and thank you so much.

Dear All, I have two questions! 1-I follow the code debugging and I guess every assembly and forming stiffness matrix is happening at TransformationConstraintHandler is that correct? 2-what is it you are doing in this piece of code? int numSPConstraints = 0; SP_ConstraintIter &theSP1s = theDomain->g...

I have the compelete main file of it if anyone wants it just let me know

Dear cobalt, I figured out how to build it, here is how: 1:use 32bit windows 2:use visual studio (because it uses visual C++ compiler) 3:create a new solution 4:add source files which are in quickmain project to it as source file(main.cpp,elemen_API.cpp,vc2005.cpp) 5:find all header files *.h files ...

Dear All, I've been trying to solve example 1 by C++, first the console app. said that there is no node 5 in domain so I change SP_CONSTRAINT arguments to these SP_Constraint *sp1 = new SP_Constraint(1, 0, 0.0); SP_Constraint *sp2 = new SP_Constraint(1, 1, 0.0); SP_Constraint *sp3 = new SP_Constrain...
