    Dear All,

    Has anybody ever observed positive displacement in Gasket element in Ansys.
    My results are showing small amount of tension created on gasket.

    Is it advisable to use contact elements along with gasket, How to ensure connectivity in model in this ase. I am getting some zero piot error, stating that model is not fully constrained.

    Awaiting the expert's comments,
    Thanks.

    Whwn you use contact elements you must be sure to have all your fredom degrees restrained. You may use a support restraining the direction that is not restrained by the contact.
    Some case you may use a soft spring restraint if you don´t want to restrain the displacement in that direction.
    If you have two flanges with a gasket, your contacts restrain in the axial pipe direction, but you haven't restrained the gasket to turn aroud the axis or to get out of the flanges.
    Your solver must know that displacements are restricted, if not it will displace the part to infinite and you will have error message.
