    Hi, I take advantage of your willingness to ask a really beginner question.
    The scenario is modelling a unidimensional simple beam system (in ip: Saint Venant or Tymoschenko).
    I understand there’s a default of 5 stations per element for running the analysis (or at least for the output results).
    question 1) is it possible to change the number of stations? (I’ve noticed that if I load the single-element-beam with an irregular load, the stations for analysis are increased automatically to far more than 5, but there seems to be no control of this adjustament)
    I saw in one of your tutorials a cantilever beam modeled with several distincted finite elements, and I get this should be the most proper way of modelling in Fem, so:
    question 2) is there a way to accelerate/automatize this way of modeling, for examble by splitting a given element (a beam) into a number of sub-elements, possibly controlling the number of sub-elemts or the sample pitch? Maybe this process is supposed to be done externally and imported as csv or dxf?

    Thank you

    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
