Hi, I am trying to run a simple stress analysis on an assembly using a static analysis, but I keep getting the error:
"The model is insufficiently constrained for the analysis. Please review the element connections,
properties, and constraints in highlighted entities. If this is a modal analysis, then you may be
able to obtain a solution by requesting additional modes."
I have defined:
-hole constraint in all directions on latch
-surface constrait on all pin surfaces in all directions, except X (same direction as load)
I tried doing the same analysis on a single part (rather than an assembly) and it works fine.
Does anybody have any ideas how to resolve this issue?
Thanks a lot
Solved! Go to Solution.
Is the latch fixed so that it can't move using a displacement constraint?
I'm assuming the pin has some freedom to move. The pin is fixed in what directions using a displacement
The latch is constrained in all directions in that hole using a displacement constraint.
The pin in constrained in all directions except X (same direction as load arrows in first picture) using a displacement constraint.
The reason the pin is much more constrained is because the error screen always points to the pin "elements" (as seen on the Error picture), so I tried many different constraints:
-Surfaces---->Individual----->Surface Set (all surfaces on pin)
Heres some other views of the error:
Take a look at the attached file. It might give you some ideas.
I made a tank model which is closed all side and applied pressure from inside, during analysis model failed in meshing, while check in review geometry and auto-gem, there is no error, please solve this issue
i had already check factors Denisity, Young's Modulas, and Possions.
