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.
Hello,
First of all, thanks for your interest in NextFEM Designer.
Unfortunately we cannot provide videos, because we officially use another solver, which is built-in. You can find a manual here https://www.nextfem.it/it/opensees-pre-and-post-processor/If you can switch solver, use the one included in Designer and keep working with hinges.
If you like to maintain the use of Opensees, use separate elements for hinges.In the attached file, hinges are modelled inside the beam element (dispBeamColumn), so they cannot be displayed since they formed into the fiber element.
It depends on how the plastic hinges have been modelled. Please upload a simple file to let us check.
Dear User,
thanks for your interest in NextFEM Designer.
Regarding your model, you can use nearest element. Elements used are linear, the temperature displayed in “Area Temperature” results is the average of the element nodes.
If the mesh obtained is not satisfactory, you can decide the mesh size in Tools/Options/Solver tab/Mesh size for IfcWall.
The upcoming version 1.4 will have a new item inside Extract Data command specific for retrieving nodal temperatures.
regardsDear Stephen
firstly, thanks for your interest in NextFEM Designer.
Circular sections and pipes are treated inside the program as a series of linear segments. You can see all the points used from Edit/Sections/pick a circular section/Edit properties button/By points tab.
This is the reason why you found a little approximation. This can make a comparison more laborious (even with scientific notation?), but this will not affect quality of results.
