Boundary condition - how to fix only one DOF ?

cashancashan
Hi.
Maybe it is funny, but I don't know how to fix only selected degree of freedom.
I default option see "full fix" only.
How to fix the only rotation at one axis or displacement in one direction ?

    for first 3 DOF select displacement constraint
    select either direction X Y or Z
    and leave deflection distance as 0 mm

    similarly for node rotational DOF
    select either direction X Y or Z
    and leave rotation angle as 0 degree

    Thx. It is Working.
    But it is not easy to use :).

    Could you clarify what's not easy? Finding them in the list or setting the parameters on the big form or something else?

    Not easy because i understand that i should add fixation in each direction separately. In other word - i have 3 different BC if I add a "symmetry" (1x displ. + 2x rot.). In other tools/softwares I can select node/geometry and define which dof should be fixed/free. It is so faster...

    I see. Thanks. Though for symmetry, you can use frictionless support instead which is much easier as long as the element surfaces are all in the symmetry plane.
