Sounds like the constraints are not modeled correctly... It might be worth attaching a screenshot or sketch of what you are trying to do.
Also, assigning 16Gb of solver RAM sounds way too high. Unless the model is enormous (millions of equations/DOF) then you won't need that much. There are...
Creo 2.0 M060 was *certified* with a technology stack consisting of nVidia K2 graphics board, Citrix XenDesktop and an IBM IBM dx360 M4 server. In this case the nVidia graphics has to run in PassThru mode (one GPU per user). In subsequent newer releases (current is Creo 3.0 M010) the...
And I meant to add that when selecting "nonlinear / use load histories" you'll need to choose nonlinear deformations for the dialog to accept the analysis. As I stated previously, using load histories for a linear static analysis is meaningless and Simulate will (correctly) prevent you from...
There's a check box near the top of the Analysis creation dialog. It is labeled "Nonlinear / use load histories"...
You can then choose whether you want to use the large deformations (nonlinear geometry) solver or not. You'll notice now that the loads have a time dependence button next to them...
Simulate can certainly handle time varying loads, but you have to ask it to do so in the correct context. To start with, a linear static analysis is not the right context. But maybe you want a linear dynamic analysis, which Simulate can handle. But given the slow application of loads, I don't...
Of course Corus is absolutely correct in this case, the use of symmetry makes the most sense! In other cases where you cannot exploit symmetry it is worthwhile to understand how to use the 3 point constraint technique (as I described.)
This is a common issue (actually a fact of life) with any FEA you choose to use. You need to make sure that the body is constrained correctly to eliminate rigid body motion (unconstrained translation or rotation) but allow it to expand freely in the required directions.
For your cube (or indeed...
You could connect a datum point using rigid links (or springs, or weighted links, depending on whether you want to model the stiffness of the bearing itself). Create measures as you suggest for the location of the datum. Then create a computed measure - this is an incredibly useful tool where...
Just to clarify/correct the above post, there are actually a lot more differences/enhancements in Creo Simulate 1.0 compared to Wildfire 5.0 than just the name...
In fact the Creo Simulate 1.0 release had a large number of solver/functionality additions:
- ability to perform contact analysis...
ddallup,
Is the Nylon_6-6 material you refer to one of the defaults? Might it be a carry over from a previously user defined material? The NYLON material that ships with the software has the all the correct mechanical/thermal properties needed for analyses.
The Hardness parameter that you...
Maybe this question is best posed to the Solidworks section?
However, if you are using Creo Simulate then you can do this type of edge/surface/volume subset using the Regions toolset in the Refine Model tab...
Agreed! And with one additional case that benefits multi-cores - if you use PDMLink then the check-in process is threaded which means you will be able to continue to work effectively in Creo while a big check-in is cranking away. I think an 8 core machine is pretty standard these days, but...
Not sure I get the FUBAR reference, but just FYI the Creo release of Simulate was a big one, with the following major improvements: Large deformation contact, coupled nonlinearities, load history controls, 2D Axisymmetric nonlinear, nonlinear springs, solid bolt preloading, temperature dependent...
Tantax,
In order to see what I described you'll need to check the box (shown in your attached picture of the dialog box) that says "Non Lineare / Utiliser les historiques de charge"
If you need to look at the contact stresses between the board and the ground, then certainly a contact analysis will be required. Sounds like this is the direct you're going from your last post. But remember that you'll need to constrain the ground too... Fully fixing it underneath might be a...
Wondering if the original poster (cmosen) has troubleshot this yet? Questions like this should never be left to gather dust on the internet ;) There's a lot that can be learned by everyone.
There are many ways to approach offering help for this, and certainly a close look an units is always...
I suspect your units of rho are wrong.
Remember that in NmmS system of units (where Pressure/Stress is in MPa) then the units for rho will be tonne/mm3
i.e. water's density is approx 1e-9 T/mm3
You should first create the shell pair (to compress the opposing solid faces onto a single shell). You can then create a shell property (it's a separate menu item) and the assign a simple thickness, or if you use the Advanced tab you can assign a composite layup, or even type in a laminate...
There are many, many pages that could be written about this (!) but just a few notes from my experience using Creo Simulate (I started with RASNA Applied Mechanica back in 1995 BTW)
- in most cases the default mesh and SPA convergence will give as good (sometimes better) accuracy and do it MUCH...
