    attached a model input files, thank you for investigate further.

    or maybe shell element type being used in default of NextFEM also problematic when mixing, exporting to Tcl shown ShellMITC4 for quad and ShellNLDKGT for tria. Is this possible to select another element type i.e ShellNLDKGQ, ShellDKGQ or ASDShellQ4 for quad and ShellDKG, ASDShellT3 or ShellANDeS for tria?

    hi, this is similar feature i previously ask. Possible trough de-activated Auto in properties and defined input value manually, add column in table menus as multipliers can be useful.

    hi, i tried split a member manually and shown OOFEM result to be consistent, so i doubt your Etabs results.

    probably i miss something about improvement, it was available at Options and preferences / Misc / OpenSees output / Interpolate diagrams on beams. However, click Results / More output stations did not display as expected.

    well that’s great for Eurocode users, personally i tried to adapt or extent to conform American building codes.

    i’m not yet familiar with NextFEM script language and needed to learn first (probably understandable), detailed of documentation can be found in SAP2000 or Code_Aster. My hand calculation still using oldest one, a newer has more complex due to iteration and shear checking.

    hi attached manual hand calculations of concrete shell reinforcement, some verification also provided. Please consider to be implemented due to usefulness, thank you.

    hi, let i share experiences of p-delta analysis in NextFEM: large test i took has shown all results in good agreement with another FE software i.e SAP2000/Etabs, Mastan, STAAD, RISA. Only some minor discrepancy is in shear force distribution curve, OOFEM solver can consider shear deformation (Timoshenko) but OpenSees can not.

    actually limit number of stations are available, so many thanks.

    thanks for explanation, add number of stations may help for this. Maybe in setting option menus, it allows for 10 divisions instead of 20 to make it less dense.

    thanks for the hints of work around for element stiffness modification. Maybe, it can be useful when allowed to input as formula, e.g =0.00026667*0.7 to easily remember and modify.

    great news it has been implemented, only in plot results has problem, and it will be fixed in next release. i checked again for OpenSees solver by exclude/deactivated shear deformation and i can confirm also, so many thanks.

    thanks for clarification, hopefully there’s improvement in future versions. Meshing of single quadrilateral shell element (arbitrary geometry nodes) by edge division is a common task in structural modeling.

    thanks, there’s placed at another menus even it seems not exactly the same. Element stiffness modification of beam or shell element can be assigned independently of axial, flexure, torsion and shear e.g 1.0A, 0.7I, 1.0J, 0.7As
