Thank you. you are right. but if the load type is changed to element load, there will be some errors. Probably because corotational can not be used to transfer elemental loads. However, I also found PDelt is not working for the elemental loads too. And this notice can not be found on OpenSees Wiki. ...

Hi there, I tried to do 3D analysis with dispbeamclolumn element. A cantilever with point load at the end, comparing the results of Linear and Corotational transformation. Because the displacement is small, the rusulsts should be very close. But they are very different indeed. Linear Corotational di...

Hi Frank, How are you? I have a problem in the design of input of data from the interpreter. I am planning to input a set of data from the OpenSees interpreter, but the number of these "double values" could vary from a few to hundreds. If I use only "double" in the constructor, I...

Hi all,

Can anyone say something about it.

Thanks a lot.

Thank you, Frank. But I still have some I do not know. "open corresponding windows project," There are 25 projects from "actor" to "utility", which one I should open? or creat a new project? or the other project? "remove other material or element .h and .cpp files,...

Thank you very much for your reply.

I have read the dynamic api, and I noticed the files in OpenSees/SRC/PACKAGES.

Supposed I have finished the *.h and *.cpp files, what should I do next?

Thanks again.

Hi,

I am going to write a new material and add it into OpenSees. But I am not clear the whole progress of it.

If someone could give me some information of that, I would be very appreciate it.

Thanks

Hi, I tried to add temperature load into a beam, but got the information: "WARNING: CTestEnergyIncr::test() - failed to converge after: 6 iterations NewtnRaphson::solveCurrentStep() -the ConvergenceTest object failed in test() StaticAnalysis::analyze() - the Algorithm failed at iteration: 0 wit...

Dear all,

I want to add the subroutine into the software, so do I need to put it into the dinamic library? But where is the dinamic libray? Otherwise, where should I put the subroutine?

Thanks a lot.

Hi there,

I could not find anything about tempratrue load from the manual. I would like to know how to put temperature load on a member or node. So where can I find that document?
