Hi, I'm new to Parallel OpenSees and have tried several times to download the Parallel OpenSees Executables from the link below but all the attemps were unsuccessful. However I see here people are working with it and ask question. Can you tell me where exactly I should find the file for download? ht...

Re: OpenSees Lab on NEES hub

Thanks Frank for your reply, 1) The only commands that I have in my scripts to account for the parallel analysis are as follows: set parallel 1; # 0 -- sequential run (e.g., on PC) # 1 -- parallel run switch $parallel { 0 { set solver "SparseSPD" set outfmt "-file" } 1 { set solver "Mumps" set outfm...

OpenSees Lab on NEES hub

Frank, 1-I tried to run my model using OpenSees Hub and it took 15 min and 50 sec. When I use my own computer it takes 14 min 58 sec! Since it's supposed the NEES hub be very very very faster than normal PCs Do I need to add any command to my code or do I us the NEES hub tool wrongly? 2-I have still...

I could not correct the possible mistake in the model. would you please check the part that I paste here? the warning is in this part and is about node constraints.
Thanks in advance

Dear Dr Silvia, Thanks for your kind attention. I have four levels and 5 bays in my model. The label of nodes are defined as nodeID= 10*level+bay .There are hing at nodes in bay 4 and 5. (for example for level 2 the nodeID are: 21 22 23 24 242 25 252 26 263 264--node 24 25 and 26 are hing). Accordin...

Using Diapheragm with hing simultaneously!

I am trying to build a 2D steel frame model which has 3 story and 5 bay in each story. the first three bay beam-column connections are rigid but the two other bays have hing connection. To define a hing connection in opensees one should define two point in one coordinate and constraint them by means...

No! The SAP model does not have fiber section. What is the influence of fiber section in period?!!

Period Difference between SAP and OPENSEES

Hi I have made a 6 story steel frame building in SAP and OPENSEES but I get slight different period from them! What is the source of such difference? SAP period:2.53 sec OPENSEES period:2.35 sec I have used nonlinearBeamColumn element with fiber section. I should mention that masses and sections and...

Dear Pejman
I want to analyse the model to find the critical angel. What you mentioned is the design code recomendation for desiners. I need to surf all incident angel to find the critical direction of a nonsymetric structure. How is it possible in opensees?

incident angel

Hi In my nonlinear analysis I need to know the critical angel of the structure, so I need to impose the earthquake record in all angels to the structure. In Etabs, there is an option to introduce the inciding angel of the record, but in opensees I have not find the same option. I want to know how I ...

BASE SHEAR RECORD

Hi I asked this question before: " How can we record the base shear? should we use the force recorder for first story element? " and silvia answered me:_______________ " it's better to use the node recorder with the support reactions, easier and faster ." Now my question is what is the command for n...
