Thank you so much.
I changed the solver to OpenSees. Now it runs but still, I cannot import the output files :(
Could you please take a look at the attached file?In the following of my comments, I would like to add that recently I made a Matlab code for generation of the mentioned “recorder” command. For a 2-bay and 2-story frame, 8000 commands were generated (total number of fibers = 8000).
The volume of files was over 14 GB!I think if NextFEM is able to do such post-processing it would be great!
Hi
In my opinion, to monitor the formation of plastic hinges I found the most accurate way is to check the strain value in each section.
As you know, in OpenSees we mesh the section to several fibers.
Using the below command we can get the values of strain in each fiber for the integration points (usually number of integration points is 5; so we have 5 sections).ecorder Element -file $dataDir/StressStrain51_Sec1.out -ele 51 section 1 fiber $fiberCoordinateZ $fiberCoordinateY stressStrain
…
ecorder Element -file $dataDir/StressStrain51_Sec5.out -ele 51 section 5 fiber $fiberCoordinateZ $fiberCoordinateY stressStrain
…We should extract the maximum strain among the fibers of each section. Then, we can compare it with the yield strain (e.g. the attached photo show this ration in 5 stations (integration points) for each element).
This technique needs to generate many many output files (above command). But I do not know that is NextFEM able to do such post-processing or not?
thank you for your reply.
I tried to run your tcl sample file by NextFEM. But I faced an error message (please see the attached file).
Could you please let me know how I can fix the problem?Thank you for your kind comments.
Can we connect the opensees fire to NextFEM?http://openseesforfire.github.io/
As you know, opensee fire has an .exe file. Can we run the model in NextFEM with opensees fire commands?
