Hello Chris,
what is a cam-pair? Can you give me an example in pictures or video how to use a cam-pair? That would be nice.
Thanks, Max

Re: Problem with Mechanism Connection
It's just a cam follower. To Tim's point/question - is your goal to simulate the dynamics of your system, or simply create an animation of how it is supposed to operate? Your answer to this will have a significant influence on the approach you take to solve your problem. If it is a true dynamic simulation you wish to conduct, you will need to create a proper cam-pair to have it behave properly ...or you could also define a limit to the slider joint with a CoR to have it rebound as it would with real hardware.

Are you using an elastoplastic material model?

Moment of Inertia Along Length of Part
I understand well how to find the moment of inertia at a plane through my part, however, I would like to know if it is possible to find the moment of inertia (in one given direction) as a function of the distance along the part. My main purpose for doing this is to find the location and value of the minimum moment of inertia. It is a complex part so this cannot be done easily just by inspection.
Any help is greatly appreciated!

Re: Moment of Inertia Along Length of Part
You can do this pretty easy with a user-defined analysis (UDA).
1. Create a curve along the geometry in the direction that you want to measure (sketch or copied composite curve) along the surface or centerline.
2. Put a field point on the curve.
3. Create a plane on the field point and normal to the curve.
4. Create a X-Section Mass Properties analysis based on the plane, save as a feature (make sure to select the parameter(s) you want to graph from the Feature tab).
5. Group the field point, plane, and analysis.
6. Run a UDA, select the group that you just created (probably selected already) and the parameter that you want to graph. You can change settings, export to Excel, save the analysis for later, etc. all from the UDA.
Thanks,
Roger

Re: PTC_TENSILE_YIELD_STRESS
Denis, please check if you have the stress-strain response set to "Linear".
If that is the case, the system should not complain about yield stress.

Re: Problem with Mechanism Connection
My goal is to simulate the dynamics. Please watch the Video A1.mp4, that is the mechanic I want to simulate. It only works in the video because the upper parts are depented on time. For example: ServoMotor1 from START till 2.45; ServoMotor2 from 7.55 till END.
When I define a limit to the slider and a ServoMotor from START till END, the simulate stops with message: assembly-anaysis failed.
I also tried to define a cam follower but I don`t have the knowledge to do this. I think a example could help me...

Re: PTC_TENSILE_YIELD_STRESS
So in the material definition box for the stress-strain response it says, "linear"?

creo interface questions
I am new to Creo,
We try to run a simple FEA analysis for pipe systems using creo simulate.
IN ANSYS, All the interfaces/gaps between the pipes can automatically detected---automatically assign contact, even if there is a big gap, still can "force" them to contact each other by using "pinball", as long as pinball size >= thye largest gap between pipes.
So I wonder if creo has same function to automatically fill those gaps automatically?
Thanks

Re: Simulate Results Definition (.rwd) Files
This appears to have been implemented in Creo 3.0 M080. I can now open multiple .rwd files by clicking on New Template.

Re: creo interface questions
Well, depends on what you mean by, "contact"; are we talking stiffness dependent behavior or just the ability to tie interfaces together? If it's the former, then yes (you can adjust the global definition under "Model Setup" by setting the default interface to "contact" and adjusting the separation distance). If it's the latter, then you'll need to ensure the surface/edges are coincident (or manually tie them with rigid links or weighted-links+springs).

Re: creo interface questions
Hi Hua,
I'm just curious as to why there would be gaps in your pipe designs? To detect contacts automatically, see below image.

Re: Moment of Inertia Along Length of Part
I was able to do all of this until I found that I needed the Behavioral Modeler. I will work on that. Thanks for the help so far! This seems like the correct method.

Radiation heat transfer
I am using Creo 3 and trying to do heat transfer analysis using radiation heat transfer. Does anybody know where Creo keeps the Stefan-Boltzmann constant?

Re: Water animation in pump
There are not many ways to do this. However, your presentation may benefit from something like a sphere being moved through the valve if you are asking for motion. Other's are perfectly comfortable modeling little arrows in their valve in a static image.
I did do a feature that looks like a moving fluid but it really doesn't lend itself to an internal path.

Material orientation setup
I am trying to figure out how to use the material orientation menu on creo parametric 2.0. I created a new orientation and selected my coord. system but I don't understand what the 1, 2, 3, X, Y, Z and "rotate about" are for. I would like my material to be oriented along the X axis. can someone help me set this up?
Thanks

Creo Simulate tag color
I have been looking all over for the setting to change the color of the text in Creo simulate tags (i.e. Dynamic query, Model Max, etc.) In most cases most of the result model is dark blue, it is really difficult to see the black tag text. Is there a way to change it to e.g. a bright manly pink so that is clearly visible at all times? Below is a screenshot clarifying my problem.
