Which Transformation constraint handler do I have to use?
As by preceding post, it seems all of them lead to the same result.

Re: MultipleSupport output
yes, constraints Transformation, but I get zero accel and vel also with Plain and Penalty (Penalty gives nearly 0 at constrained nodes).
Lagrange gives error if no alphaM/S are specified.

MultipleSupport output
Hi all, I've a model in which I imposed the displacements to the ground (in order to simplify, in this sample I used the same TH): From: https://opensees.github.io/OpenSeesDocumentation/user/manual/model/multiSupportPattern.html I read: The results for the responses at the nodes are the ABSOLUTE val...

Re: ShellMITC4 stress calculation
I think I found the point - theElement->strain was always zero, due to the fact that
does not set any trial strain on the element.
I used this because at this stage my model is linear, anyway I turned into and now I have forces.
Code: Select all
algorithm Linear

Please tell about the error encountered. The DLL was updated a few months ago. If you can, uploading your model will be of great help.

Linear stability analysis?
Hi everyone,
can OpenSees perform linear stability (buckling) analysis?
I cannot find any reference on that, and I've never seen any geometric stiffness matrix in the elements' code.
Thanks

Re: A problem with adding a new material
I'm trying me too, but I get an overflow error when trying to read "theParam" array. It seems that the c_f_pointer it's not working.
Moreover, you must correct the "if results != 1" in TCLelement_api in "if results != 0".
Still looking to solve...

New software for pre- and post-processing
Dear all, it is available from now a brand-new software that supports, amongst the other features, pre- and post- processing for OpenSees. Some applications will be presented in the upcoming OpenSees Days Italy in Salerno. It can be downloaded from http://www.nextfem.eu and it is free. I kindly ask ...

windows DLL for new system
Deaf fmk,
is there an example for ms visual studio on how to compile a new system as external DLL?
if not, can you tell me please which template I can use (maybe the one for the new element or for newCommand)?
thanks in advance,
Giovanni

Dear fmk,
what is exactly the difference between OPS_GetNodeIncrDeltaDisp and OPS_GetNodeIncrDisp in the element APIs?
thanks,

The point was the name of the libs. It is necessary to publish some instructions on the wiki.

Re: How to compile OpenSeesMP in Windows?
dear fmk, thanks for your reply. However, it seems harder that described. As I said, I got mumps (and blacs) and scalapack for windows, but the referenced LIB files in OpenSeesSP and MP projects are not so clear. I found: blacsCinit_MPI-Win32 blacs_MPI-Win32 scalapackd mumpsFortran mumps Can you pro...
