You want to simulate newto first law?
What you expect to get as result? :)
There are several answers for you question.
First answer is virtual wall. But you shall answer my question first. What you expect to see/get as result?
I want displacement on points on the outermost edge as shown in this fig. Because of the constraint i hardly get any deflection there.
Also there is no place where i can constrain the model in y dir. (i have a force that is applied on the top surface).
Ideally i would want the highlighted region to deflect in -y direction under the action of pressure and be constrained in +y direction (No deflection under the action of load on the top face).
Please let me know the ways of doing that.
P.S - The part in consideration is a circular part. I have consider only a quarter section as the part is symmetric and in order to constrain the model in all degree of freedom such that the model does not fly off.
Sandeep, the Y direction restraint that you've chosen sets the nodes on that face = 0 displacement. Meaning it won't move in either direction. Go with Rado's suggestion of a virtual wall or contact between your component and another component with no penetration contact sets between them. That way they can separate or interact.
Please have a look at my reply to Rado, and let me know your comments.
virtual wall or contact.
with a fixture you're restraining both directions. there is no fixture that lets you restrain in one direction and not the other. that can only be done with contact.
