i start in preesre vesel study ( static study ) . i have this error meesage when i run the study .
i have defined all solid and shell faces and al bolts and all bondedd contacts
see the attach picture .
hope to help me in this issue
It looks like your fixture is a single point on the bottom head. I don't think that is going to be enough to hold this in place. I would suggest adding your supports (or at least a simple representation of them) and use them as your fixtures.
The other issue could be lack of contact and connectors. Use soft springs to find all of these issues or suppress all the parts and add one at a time to find the ones with issues.
thank you very much .
Mr Patrick O\'Hern :
I tried to fix the model more then one way and i still have the same problem .
Mr Jared Conway :
I realy defined all contacts between part . and tried to use in soft spring byt this choice is not logical for pressuer vessel cause we will get large desplacmet in any load values
i will try again to define th contacts
thank you for your help and i wating you replay for other solution .
I'm not totally following. Soft spring is for troubleshooting. It sounds like you get a large displacement error when implementing this. This means you likely have missing contacts or connections. Either build the simualtion part by part or fix every part individually until you find out which one is moving causing the errors.
