Dear Developers, Is it possible to introduce in the C++ file some code that would print out desired results to a file? More exactly, I am interested in printing out the stiffness matrix for each analysis step. It is true that I can print the values in the prompt window, but I makes the calculation v...

Dear Community, I would like to consider a new structural element with 4 nodes, 11 springs and 12 degrees of freedom. I believe that there are some mistakes in the OPS procedure that I wrote at the beginning of the .cpp file, since I obtain this error: UniaxialMaterial *getUniaxialMaterial(int tag) ...

This is the setDomain() method. The 4 nodes are identified, but somehow the element is created only with 2 node. Any ideas? void SPPlastic::setDomain(Domain *theDomain) { if (theDomain == 0) { opserr << "ERROR : SPPlastic::setDomain -- Domain is null" << endln; return; } // first ensure no...

Dear Community Members, I am trying to build a 4 nodes joint model, based on BeamColumnJoint2D element. After creating and loading a frame using the joint created, it looks like the 4 nodes are not connected. I thought the error comes from setDomain() function but it's not. Does anyone of you have a...

Dear Community,

I have .dll (code for element), .tcl and OpenSees.exe in the same directory.

When I try to run the tcl file, nothing happens? No errors and no results.

Does anyone know why? Is there anything more to do when running with codes in dll?

Thanks in advance!

Dear Community,
I am intending to perform a 2 step analysis.
Is it possible that in the 2nd step to remove some of the BCs defined in the 1st step? and how?
Thank you!

yes, but that value of the force will be equal to the one in the second case, so both cases have the same value of the force, right?
case 1 => force x load control x no steps = 250 000 * 0.1 * 14 = 350 000
case 2 => force x load control x no steps = 350 000 * 0.1 * 10 = 350 000

Dear all, I am performing some research on steel frames and joints. Using the same type of integrator (load control) with the value of 0.1 and changing the number of steps and the value of the applied force, I obtain some very different results. Please check the results file in my dropbox: https://w...

It's working, but not from my university due to the firewall. It might be your case too.

I also ran the code. It works fine, and yes, it prints results to the *.out files.

Yes, I do obtain the same errors, almost for one week already.
Their website was down in the last weekend, probably some maintenance is done.
Let's hope it will work soon!

Which python version are you using?
