Exclusion of a component
Hi all,happening to have one or more component of an assembly that you don't want include into the analysis because, for example, it is so much rigid respect the others. At the same time you don't want...

Hi all,if I want to analyze an assembly with the symmetry constrain I need to "cut" the entire assembly before to enter in Mechanica.But if the cut is passing trough a hole where I want to put a screw...

Hi, You cannot 'cut' a fastener idealisation in half. If you have a symmetry plane that passes through the fastener then you have to mode the fastener as a solid. Regards

How can I set a preload force modeling the screw as a solid?I suppose I need to set a free contact region between screw and hole.

I've done this before by adding a point mass at the CG of the part to be removed and then attach it to the part. If the part transfers a load, I've modeled the connections of the point using beam...

However putting on the component the control of exclusion should lighten the resolution of the system of equation because the program does not search the solution on the nodes of that component; I...

Yes, it will be faster. It limits the polynomial order, and excludes them from some results calculations if you tell it to do so in the analysis properties. It just might be difficult to define the...

They are bonded by the default "bonded" interface since in reality, the components are sticked together with the epoxy resin acts as an adhesive "glue". If I understand Steven correctly, what he...

I have this assembly, already simplified for the FEM analysis.It is an equipment testing.I need to see the displacement (especially the vertical one) ander the mass load of the components.Some...

Giulio, I took a brief look at your assembly, and here's what I'm seeing that needs attention: 1. The model won't mesh because of invalid fasteners. You have fasteners going through holes of...

I've already done the static analysis and I've not have problems with the meshPS: I use WF5I didn't know that. I'll take note. Thanks.I've done the analysis with "Fix separation" on Automatic; like in...

Hi Giulio, 1. Your model would not mesh in Creo Simulate 2.0 (code M080) as shown below. I'm not saying it would not mesh in earlier versions. 2. When running fasteners with a preload, you will...

Very nice; I accept gladly any documentation. When I have a multi-body assembly with fasteners I need to specify a contact region "contact"? But, it does not would have to make this the program...

The attached document shows why you need two runs for fasteners.

Here's another example of pre-loaded fasteners using two runs.

Isolate for Exclusion is a mesh control used for convergence. Specifically, it tells the software to exclude the selected from consideration in the convergence study. The only way this could help you...

I played around with his model; looks like it was an issue with the fastener "M8_2"; the model meshed after re-defining it.

Re: Fasteners on symmetry plane
I believe you said in your other thread that you're using WF5 (I'm not too sure if this feature was added in), but there is a pre-load for solid elements. If this feature isn't in WF5, then you could...
