    Question Meaning of symbols

    Could anyone explain to me what the blue highlighted symbols in RSAP mean?

    OK think i have figured it out. It appears they show up after a finite element mesh has been generated for a slab.

    Looks like you have defined a shell like as rigid diaphragm in shell type defined, and you have blocked rotations about x and y and z translation,
    reed in help more about shell type( shell, diaphragm, cladding , .....)

    Or check if you have defined any point support.
    The symbol looks like user defined support with x and y rotations blocked and z translation blocked.

    OK. actually the slab has been modelled as a flexible diaphragm with blocked degrees of freedom as you described ... thanks

    Strozy: the symbol in the middle of the diafragm is a support, automatically added when model is generated. This panel is defined with 'flexible diaphragm' calculation model. There are generated finite elements to model bending stiffness. Additionally there are generated rigid links between elements nodes to model horizontal rigid stiffness. All the element nodes are rigid link slave nodes, while there is generated a master node at the panel gravity center. This additional master node is automatically supported by UZ, MY, MZ fixed directions, what is visible with this symbol.

    smm.144: by default the local axis coordinate for panels are displayed with bigger perpendicular z axis and smaller tangent x,y axis. When the x axis direction for a panel is redefined by the user, then this fact is reported graphically by dicreasing x,y symbol display.
    So if the x,y axis are as big as the z, it means that the x axis direction has been modified comparing to the starting position.
