    Hello,
    I suspect this error does not rely on us, anyway please send your model to see to check.
    By what I see in the picture, simply your model does not converge using OpenSees solver.

    regards

    Nodal temperature time-history now available in patch no. 1 for ver.1.4, see https://www.nextfem.it/it/patches/

    Create new nodes and new elements, or create only border nodes and mesh automatically with the planar mesher.

    Simply add a “layer” (made with some elements) with other caracteristics, representing the fireproofing.

    Extract data/Nodal temperature for now does not allow to get temperature series over time, but it can export for the same time all nodes. This feature proposal will be inserted in the list for the next patch.

    From Edit / Functions…, pick the series you want to add from Add new series menu.
    Then click on Add in the “Series Tools” box, and again Add button in the “Add Function by points” box.

    The function must be associated to the HT analysis in Assign/Analysis settings.
    Hope this helps

    Hello,
    strenght under fire of the section is controlled by conductivity and specific heat – you can always add another layer for fire protection with different properties. There’s a sample here (in Italian): https://www.nextfem.it/it/analisi-termica-di-sezioni-in-c-a/

    In the tutorial, we supposed the bottom edge was the only one exposed. This is a typical situation for a beam. For columns, all edges are exposed. You can apply fire on any edge.

    Version 1.4 is out, please reinstall and retry.

    Version 1.4 is out, please reinstall and retry. Also set again Solver path for OS.

    Fire analysis for sections is performed in a separate file and it’s finalized to strenght verification of that simple section. In a near future we’ll implement the analysis conducted automatically on a structural member.

    Hello,
    OpenSEES solver is not shipped inside the program, you should set OpenSEES as defualt solver in Tools/Options/Solver tab/ and specify the path of the OpenSEES solver.

    Dear Sepide,
    thanks for your interest in NextFEM Designer.
    Progressive collapse is generally conducted using explicit non-linear analyses, and even if they are supported by our solver, they’re not exposed, due to the lack of interest on this analysis by designers.
    Hope this helps in understading the progressive collapse technique.

    THe program requires you to load the TCL input file prior to be able to load results. Provide he TCL for the model and a new mask for importing results will be shown.

    Yes, if you load a TCL file including such commands, you can launch it and use the program as a post-processor. However, the usage with Opensees fire has not been tested.
