How to constrain nodes in positive axis only? (I-deas Master series)
(OP)
Hi guys,
I am trying to constrain(arrest) the movement of a bracket surface in positive direction only(say Y-axis) and let it to be free in -Y axis.and it has to be free in all another axes.
I need to do so , beause the surface i need to arrest , as said above is in contact with other part.Just like anti rotation flange.
Is there any option in I-deas software for this..
Please help me..

But i am doing linear analyis only..
Ok.. how anti rotation flange can be simulated in FEA.. i mean what kind of restrains i have to give..

Please anyone clarify this linear, non linear concept
RE: How to constrain nodes in positive axis only? (I-deas Master series)
Non-linearities in a model can be introduced by materials (eg plasticity), geometry (ie non-linear geometry such as displacement-dependent stiffness or large strain/displacement) or through other changes in model stiffness (ie contact, such as stick-slip). As mentioned, you will likely need to consider some form of non-linearity to achieve what you need - the good old-fashioned gap element might suit your needs here.

I found one element type called "constrain elements" in I-deas SDRC.
Will it be possible to solve that contact issue.
If not please consider any method to simulate this..
I am attaching the illustration i need to constrain.
