Re: Multistep Analysis?
Hi Steven, Residual stress from temperature is a non-linear material thing. So you also need to define non-linear material properties otherwise the study will remain static in the sense that unloading...

Re: Can one controlling element growth after specifying surface element size
You can specify a surface element size and a low value for aspectio ratio (AR). Default A.R. is 30, which means that an element adjacent to a surface element (inside the volume), can be up to 30 times...
View ArticleRe: Structural results evaluation: deformed display scaling percentage meaning
Just to add to Charles' description, my understanding is that the 'percentage' option is good for checking the general deformed shape of a part - applying "10%" deformation always gives a deformed...

Thanks to all of you for your replies, they were all extremely useful. In particular, it seems I can now explain a strange behaviour (that was also one of the reasons why I opened the topic) that I was...

Hi Tommaso, The gap is not amplified, but the displacements are. If there is an initial gap and it is closed during the analysis, then any displacement scaling larger than 1.0 will show...

Charles, What would be nice is having a Design Study Revision scheme where the design study or Analysis name('s) do not change but allow you to run multiple part iterations for one assembly and allow...

Yes, residual stresses are a non-linear material thing. Advanced license. Everything else is linear elastic superposition; final result being independent of order of application of loads. Additionally,...

Details in this pic.I want that extruded portion should rotate the cylinder when it makes contact with it and then carry it in the later motion.

My first guess is to use a slot connection. You will need to model a curve in one part and a point on the other.With a slot connection the point will slide along the curve. You can specify (I think) a...

Hello all,I make a simulation of an assembly and when i see the stress results (von mises) it only shows the global values.Is it possible to have the stress results of each parts ??Thanks for your...

Re: Simulation of an assembly - How to see the stress of each parts ??
In the result definition window, click the display location tab and then select components and use the buttons at the bottom to hide or show them. This will allow you to isolate individual components.

Shouldn't be one body fixed for slot connection? Here both of them are given pin connection as each of them rotates.

I find it easier to simply mimic the motion with servo motors using specific timelines. in this case, use a rack and pinion gear connection to a phantom servo motor and then a separate servo motor for...

Here I made a test with a slot and two rotating parts. Works fine, the model is redundant, so I had some accuracy issues with the wrapped curve representing the slot. This can be overcome with some...

Yes at very first place i had a thought of using two different servo motors and then time them accordingly. But i thought there has to be some real time way where they contact each other and start...

I didn't manage to create "end stops" for the slot-connection itself. But this should be possible to achieve with max/min values enabled on the joints connecting the shafts.
