Stress Analsysis Problem?

[shreyas5]

I was working on a table for a school project in Autodesk Inventor 2010 and it needs to be able to support a certain weight. When I go to Stress Analysis, I cannot add any fixed constraints or apply force to anywhere on the table because the options are not available for reasons unknown to me. Does anybody know how I can fix this? The Table is made of ABS Plastic. I tried the Stress Analysis before shelling it and it didn't work and it still didn't work after shelling it. Is there a problem with the material I chose or the way it is built? The Table has a top with a 1yard diameter and a circular base which narrows as it reaches the top of the table. The narrowest part of the support is 1 foot. Please give me a solution to my problem. Thank you for your time, I greatly appreciate it.

Your model didn't have any material applied, but I had no problems applying
constraints or a load, it meshed and the FEA checker wouldn't allow analysis
until a material had been applied.

Possibly check your FEA process, working from LH to RH in the FEA
enviroment

1.) Manage - select your type of FEA Analysis
2.) Material -
3.) Constraint(s)
4.) Load(s)
5.) Contacts if required (not in this case)
5.) Prepare (mesh your model)
6.) Solve
