Hello,
we have compression-only (hook) and tension-only (gap) springs that works even without license. FOr their characterization, please refer to https://www.nextfem.it/it/a-survey-on-non-linear-analysis-in-nextfem-designer-part-1/
Since they are free, you can use them in your NL analyses.
Let us know if you need further help.regards
Hello,
the getMemberLength returns 0 because its argument must be a member (see https://www.nextfem.it/api/html/M_NextFEMapi_API_addMember.htm) and has nothing to do with a single beam.position1 and position2 are the initial and final position of loading. You can use 0 and nf.getElementProperty(beamID, “lun”).
In the attached image I see the checkbox just under the writing about privacy policy. By now we cannot reproduce your error, we suppose it’s depending on the system text size (e.g. 125%, which is default on 4k screens).
Hello,
we tested the installer and it behaves as expected.
You should see the following page, in which to accept both agreement and provacy policy in order to proceed.Did you updated to v1.9.1.0? If not, update now – a patch is needed. Lite version won’t be updated.
In case you have trouble installing it, please download the full installer again.Thanks for the file – please note a loadcase is needed to export to ABAQUS format.
We’ll release a patch soon. The output is attached.Hello,
there’s no difference between Lite of full version for import/export for Abaqus format. If you encounter problems, share us the model if you can. You can upload it at the bottom of this page https://www.nextfem.it/it/help-support/First of all, you have to use the version of rSpectrum included in NextFEM Designer (seek in the installation folder). The ones provided in the ‘OpenSees tools’ page is not up-to-date.
If this not solve your problem, please attach model or send it via the form at the bottom of https://www.nextfem.it/it/help-support/Hello, please find answers below:
1) NextFEM Designer has a completely automatical automeshing, that occurs only for linearly variable distibuted load on beams. Stations are automatically adjusted accordingly (e.g., in Verifications, the 5 stations of an internally-meshed elements are automatically interpolated from results)
2) there’s no need to mesh beams manually, unless you want a higher a resolution in results using uniform distributed loads. In any case, see command Edit / Divide or merge.hope this helps, regards
Dear Francesco,
thanks for your appreciation.
Regarding your issue, we know there are some opening issue for users running Windows 7, mainly related to memory usage. To solve this, activate the option “Safe mode for opening” in Tools/Options/Solver tab.
Hope this helps,
regardsHello,
NextFEM Designer supports results from 3D OpenSees model only. However, you should be able to see the imported model if elements you used are supported. If you can share model, please send us via email.Hello,
of course, look into this repo: https://github.com/NextFEM/API-Python
in particular pushover_analysis_OpenSees.pyHope this helps
