Generative Structural Analysis error: Singularity Detected in Translation (Pivot too small)

Full Error message:
"Factorized matrix computation
Singularity detected in translation (Pivot too small)
Possible Reasons: missing restraint or connection specifications.
Display deformation or displacement vectors to diagnostic the problem."
Please help me! Thanks! :)

if its an assembly, then u need to add contact constrain (or others i.e bolt tightened) in "Generative Strucyural Analysis" in each of your contact constrain from "Assembly Part"

[@johnlitoo]

Ivan Yakobus is there a way to do the test with no bolts but just a contact strain? also as I'm design a simple aircraft wing, do I need to have a contact constrain for an arrayed (repeated? aerofoil ?

[@IvanYakobus]

John McCrudden you use contact constrain when assy the parts.
then you click "generative structural analysis". Give contact constrain again in each contact, this contact constraint in GSA is to define parts can not move "pass through" other parts.

[@IvanYakobus]

John McCrudden in modul generative structural analysis, search contact connection.. expand from slider connection.
each of contact constrain should be add contact connection. please info if you've succeed

[@johnlitoo]

Ivan Yakobus Which tool do i use to do this " Give contact constrain again in each contact,"? Im just trying to sort it out and still getting the same thing - im trying to make sure that its defined can not move pass through - Thanks allot for the help!

[@enemesbee2511]

Ive tried your answer. I still get the same error? Is it because i use coincidence constrain instead of contact?

[@blackgear]

Hi man, your plate is free... İt should be fix for one way (Z direction) You should add the vertical surfaces to surface slider restraint. And the second one is, you should use contact connection prooperties wheel hub and wheel and plate and wheel surface. This is going to be lineer computation. In this video, you tried to calculate linear dynamic situation. Did you understand what I mean?

merhabalar, tek parça halinde çizmiş olduğum bir analizde bende aynı hatayı almaktayım ama sorun ne olabilir? yardımcı olursanız sevinirim.

[@ahmetumuttekin1382]

try to increase the number of clamps,I tried and it works

[@johnlitoo]

Did you solve the problem? Im trying to do an FEA on a Wing that i made but im getting the same error

[@IvanYakobus]

John McCrudden see my answer up there, hope its useful

[@kikemva]

i though i seen this before
