keep the opensees.exe in the same dierctory folder or drive where you installed active Tcl. If you are getting side to side configuration error then that is due to virus in your laptop( windows platform I am taking about).

sir,In documentation we can able to find reactions in three global directions.But to find resultant reactions at particular node is there any command? I could not find command regarding this issue.Please check.This is very important in validation of opensees.

Kindly keep the manual in web site as well as in pdf or in a zip file becuase it can be downloadable. People who don't have net facility it will be difficult to use opensees without manual.If Pdf format people can able to refer manual without internet

Thank you vesna and thank you for the reference.My intention is to validate opensees with other software then only I can use opensees in the organization.I solved so many problem intially but this validation I did not do. Initially my focus was to solve the system now I know the solution but how to ...

Dear vesna ....can you explain the concept of geometric transformation (all the three options) with an example which includes numerical values. I am facing a big problem with geometric transformations with members.Please consider a general member (inclined) for explanation.Thanks in advance for your...

Thank you vesna...thank you for the reply.I wondered initially how you got the results. But now you also came to know my problem.it was not showing but results are nonsense.So I tried to analyze the problem with all linear beam column elements (inclined,vertical and horizontal) but I am facing probl...

Dear vesna....one more clarification needed.In the problem I specified in model builder -ndm 2 -ndf 2 that means it is 2D problem and at each node 2 translations in x- and y- directions are possible no matter of rotation. If -ndm 2 -ndf 3 means it is 2D problem and at each 2 translations in x and y ...

Dear vesna..sorry for disturbing you again and again.My situation is like that please understand.I m using TCL editor version 0.3.1 and opensees 2.3.1 version.Are those versions are compartible to each other or which version of Tcl editor I should use if I want to run opensees 2.3.1 effectively. Fro...

Thank you vesna...but still I m getting nonsense results like QNAN and IND.If I keep wipe command at the top of the file then also same thing.I checked with opensees 2.3.1 and 2.3.0 versions.I could not get the results.I dealt big domain problem i.e soil structure interaction analyzed in opensees an...

Dear vesna .....I need a favour from you.I am validating openses with Staad Pro.The problem I am dealing is a simple static analysis of a truss.But while anallyzing in opensees it is becoming trivial.Can u check my script and can u update the script to run.I used all the solvers available in opensee...

Thank U vesna. thank u very much.If we give 1 then that will restrain the node. For example fix 2 1 1 1 1 1 (means node 2 have no displacement and no rotation in all X,Y,Z directions i.e. global X,Y,and Z directions.In this situation the node will have reactions means forces and moments in X,Y,Z i.e...

Vesna..... can you give me ur Gmail ID. I want to have some discussion on opensees. Actually in a command fix what actually it is taking about? This command is used to construct single-point homogeneous boundary constraints. fix $nodeTag (ndf $constrValues) ------------------------------------------...

Thank u vesna....thank u very much but the problem with clients is that they are asking validation because people are not aware opensees. Opensees is not graphical interface to understand easily.Basically opensees will be used by researchers and not popular in organizations.I used Opensees in my the...

Sir, I modelled water tank with 4 noded shell elements and pinned at the bottom in 3D in Staad Pro. I modelled the same water tank with ShellMITC4 element and ElasticMembranePlateSection as section in opensees in 3D. All the properties like thickness,young's modulus, water pressure (water pressure i...

Thank you for the response vesna. I tried with Sparse symmetric solver.If I use SparseSPD it was showing "OpenSees.exe has stopped working" in windows explorer.Please help me vesna I will be waiting for your valuable reply.
