Dear Moderator I tried several times right now but I couldn't download openseeparallel ! It says the the file could not find in the server! Has its location been changed? I really need Parallel operation because my models are so big with many details and I also need very short time steps to catch ex...

Thank you so much Dr. McKenna for reply. Do you have a suggestion for substituting a similar material instead of SMA to simulate its uniaxial behavior? If it is impossible, is there any example to help me how to implement an arbitrary uniaxialMaterial? It is indeed vital for my thesis to simulate SM...

Hi Dr. Silvia I am modeling a single bar with SMA material. I want to pull this bar in order to check out if its uniaxial material work properly. but I cannot handle this convergence error: WARNING - ForceBeamColumn2d::update - failed to get compatible element forces & deformations for element: ...

Since many operators need to know how to model a pinned or simple beam to column connection, I wrote and posted a 2D 1-story 1-bay steel frame with this feature. I hope it helps other students with confusion between zeroLengthElement and equalDOF. The results are exactly the same as SAP2000. # Examp...

Hi I'm a M.Sc. student at SUT and regarding to my M.Sc. Project I have to model a steel structure with beam-to-column connections equipped with shape memory alloys. I think I have to model simple beam-column connection and add a torsional spring on the joints with the moment-rotation response of SMA...
