Hi mannyh, You can try something like this: set out [open textOut.txt a] puts $out "Hello OpenSees!" ... set a 1 puts $out "the number is $a" ... close $out the 'a' stands for 'append' you can use 'w' to clean up your file (the 'w' stands for 'write') example: set out [open textO...

Hi ninashnash, elastic case: you can get the rotation from nodal recorders of the i-j nodes and the forces from: recorder Element -file ele1local.out -time -ele 1 localForce (or globalForce according with global coordinates) fiber beam-column element case: recorder Element -file $outputfile -time -e...

Dear Silvia and Frank, I'm modeling a 3D frame, 2x2 bays, 4 storeys and processing TH analyses. Columns and beams are fiber elements. I was using elastic shells (IsotropicElastic NDmat=> PlateFiber NDmat => PlatFiber Sec => ShellMITC4) to model the floors (R.C. thickness 15 cm/5.9 in), but I decided...

Problem solved!

The mistake was in the geomTrans IDtags of the nonlinearBeamColumn elements.
Some of them were not assigned correctly.

Thank you for your answer, Frank. The problem is in the coord. transf., though. I have to put the right coordinates in the geomTransf command. It is weird because I followed the example 7, as I wrote. I'm modeling a 3d frame in Opensees for the first time. I sincerely didn't get exactly how the 3D g...

Dear Silvia, I'm working on a 3D RC frame fiber model, 2x2 bays, 4 storeys. I am doing a Time history analysis. I'm having a problem with the geometric transformation command. I'm following the example 7 - 3D RC Frame global coordinates system y | |____x / / z I define the geometric transformation i...
