Circular Welds - Computing Mesh

113 Views, 3 Replies

I am trying to use the FEA program to find the stress in a vessel head. The head has two nozzles and each of the nozzles has a repad. I am able to add welds to the repads to connect them to the vessel head, but whenever I try to run the FEA analysis for the vessel, I get a "Mesh Error: Body Failure" for each of the welds at the vessel head. Any ideas on how to correct this? I have attached the file with one of the welds in place. ANy help is greatly appreciated.

An assembly file (*.iam) is only a list of hyperlinks to the part files (*.ipt) and a record of assembly constraints (and a bit more).

You must include the part files.

I recommend that you not include the welds in the analysis (should not be needed) and you need to indicate the Inventor version (if 2014 there is a Registry edit you need to make).

I am very new to using Inventor. All parts for this model were made in AutoCad and then exported to INventor for analysis. Where would the individual part files be located if this is the case?

Navigate to where the Head E FEA.Iam file is located with Windows Explorer, then RMB on the file and select the Pack-And-Go. It will find all related files to the assembly and place them in a ZIP file that you can upload.
