Re: Simulation status: Failed while calculating
I have checked results in simulation that had status Failed and the one which had status Running. The results were almost identical. So I agree with you that the best thing is to just ignore the...

Re: Does Creo simulate impact between two parts?
Patrick, You can create a modal analysis of the bat, and then create a dynamic time analysis to see how the bat vibrates after the impact. This is provided you know the force history of the contact...
View ArticleRe: How do I measure the torque output of a gear in Mechanisms?
Hello Cameron, in the model shown in the picture, the "output torque" would entirely be used to accelerate. In reality you want to measure the torque that would be necessary to keep the velocity...

So, at long last I've actually got an optimisation study working, and rather well. Having so far been optimising for displacement with a mass limit, I'm now trying to introduce some stress limits too....

Hello Jason, have you been able to figure out what was wrong? If yes, please let us know!Otherwise, the limitations of your license remind me of something: Have you checked for messages telling you...
View ArticleRe: Creo3: Stress doesn't change regardless of load.
I don't think modal analyses use a 'real' force value - it's more like a unit load, and I don't think that the loadset you apply are actually used (only the constraints). As I understand it, stress and...

The material properties allow to define hardness, but it doesn't look as if it is used for calculation.There is one article that says it has an effect on damping (which should be used with Mechanism) -...

Compare your calculated stresses with the yield stress for the hardened material. If the stresses are below the yield stress, then a linear analysis is valid and increasing the hardness will make no...

Re: Creo3: Stress doesn't change regardless of load.
A modal analysis ignores all loads. The stresses that are displayed shows the stresses at a "normalized" displacement of "1". The displacement you see as a result from a modal analysis is the deformed...

Non-symmetric results for symmetric model and load?
Why is it that displacement for a cone is not rotational symmetric for an internal pressure?A sample model is attached (Creo 3.0) I've brought it back to the bare minimum. 1/4 cone, symmetry, default...

Hello -- I am working with a rather complicated assembly in CREO 2 Mechanism Dynamics. Because of IP issues, I am unable to show you the model. I have rotating components, with oscillating components...

Re: Non-symmetric results for symmetric model and load?
Very interesting problem. I will take a look at it next Tuesday when I get back to my office. However, someone may have solved it by then.

I'm not able to open your model as I'm on Creo2, but when creating a similar model i find:* when constraining the symmetry planes with theta=0 the results look strange* when constraining the symmetry...

Hi Patrick Thanks for your efforts. There is also a Creo 2.0 model in the attachments. That one is 360 degrees, no use of symmetry BC's, severe non-symmetry in the results though. (see the 360 deg...

Okay disregard my previous message. I was looking at stress, and that looked okay, but displacements were unsymmetric. The results in your model are unexpected indeed. You should send this to support,...

Re: Non-symmetric results for symmetric model and load?
I get symmetric results. I tried both planar constraints on symmetry surfaces, aswell as constraining "theta"-direction in a cylindrical csys. Default mesh + SPA gives a small deviaiton from perfectly...
