You may use a support restraining the direction that is not restrained by the contact.<br /> Some case you may use a soft spring restraint if you don´t want to restrain the displacement in that direction.<br /> 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.<br /> Your solver must know that displacements are restricted, if not it will displace the part to infinite and you will have error message. </p> http://www.FEA-Forums.com/topic/32#post-41 Mon, 31 Mar 2008 22:47:51 +0000 prachi2909 41@http://www.FEA-Forums.com/ <p>Dear All, </p> <p>Has anybody ever observed positive displacement in Gasket element in Ansys.<br /> My results are showing small amount of tension created on gasket. </p> <p>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.</p> <p>Awaiting the expert's comments,<br /> Thanks. </p>
