Hi,

I am performing static structural analysis for an imported design file in .stp format.
I have removed all the existing contacts and re-created all the contacts for the entire assembly with bonded function.

I have applied only a force (F1) of 1962N(200kg) lift on the top face and a force(F2) acting as a load inside the body of 833.85N(85kg).
I have not given any supports/displacements or any other inputs.

I have turned on the large deflections to ON and made stiffness matrix of all the contacts to 0.01 factor.

Yet, I am getting the below errors/warnings:

 

Can somebody help with a quick solution!

Regards,
Rani

Hi

See this video explaining the error messages -

Also look at our other free Ansys courses on how to use and set up models correctly.

All the best

Hi,
Got it thanks!
Will check and get back if i find any further issues!

Your model is basically flying to infinity because you're not constraining it with an displacements or fixed supports. Thats why your UY value at node 303358 is 2M+
