Insufficient Contraints
So I'm trying to Run an analysis on an assembly and I am getting the error of (see picture). I have been able to run a few successful analysis but lately they are coming up with this Analysis. Any...

Something is moving without generating any opposing force. Assuming that you have constrained your assembly fully (every component prevented from translating or rotating?) then other things to check...

The assembly is fully constrained, I do have material assigned for everything (includes density and Young's Modules). The only thing I changed between the first time I ran the analysis (when things...

Sometimes the suggestion of "running a constrained Modal analysis with rigid mode search" does actually help. If you do that and animate the results, it often shows which component is...

It appears your model is a 3D analysis, did you follow the rule of constraints for a 3D analysis - rotational DOFs are not present for solid elements? Only translational DOFs can be assigned if this...

I've a vague memory of that kind of error being caused by a bad mesh -- those red elements might indicate an element connectivity problem. Possibly, higher displacements (due to changing the force...

I'm getting the same error. Their axisymmetric analysis is a headache. No real help as to what the error means or why it came about. I'm going through a simple cylindrical heat analysis, and right...
View ArticleRe: The Most Worthless Error Message
In general this error message appears when you intend to run analysis on a non-solid model.For instance a shell model, where you look only at the central fiber of the material. If in Creo you put a...

Jonathan's second reply is correct. Run the mofdal analysis, with rigid mode search.Inn the results you will find modes with 0 Hertz. Animated displacements will show you the parts that are not...

Hi All, From what I can tell, the answer is No to the question above.I keep getting a message saying "Contacts will be treated as Free Constraints" and I see no load transfer between the hyperelastic...

I got the same error message and, for my particular case, found out what the problem was. (Short answer: make sure all model geometry is selected under Edit -> Mechanica Model Setup) Here's a...

I need to calculate torque/force acting on the outer friction disc. The inner friction disc rotates alongwith the shaft and the outer friction disc only rotates when it comes in contact with the inner...

Julien, One thing to remember when using Batch Mechanica is that when you setup a Batch run, the current models and analysis setup in your pro/e session are copied into a new folder (name of analysis...

Things became rather slow and then when tyring to save the model the s/w exited. Retarting Creo was slooooow. Reboot. I can press all the buttons now. Weird goose chase. Thanks for your help.
