ok. and what about intersections in model. and
for modal analysis is it necessary to remove the same. if not why?

@Sandeep P Can you send a screenshot for what you mean by intersection here?


@Nachiket Kadu Penetration is thickness overlap & intersection is elements is completely passing through another. please make me correct if am wrong. pls find the below intersection image for your reference.


is there any manual available for optistruct keyword. can any one give link or pdf?


in image you can see red colour elements intersected in yellow that is not going to connect with rigids. only bolt locations will be connected

So anyways you are not going to have a contact there right? If so then without contact it may hardly affect the solution stiffness.


ok Nachiket. thank you. i am able to get opti manual in help. can you attach if you having ?

Hi Sandeep,
Intersections and penetration will affect the results. For example in non-linear analysis penetrations may produce unwanted stresses around zones and the load transfer maybe not as expected.
