    Spiral bevel gear analysis

    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...

    Running Creo Parametric / ProE on a centralized virtual server

    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...

    Forces varying with time?

    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...

    Forces varying with time?

    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...

    Forces varying with time?

    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...

    Simulation of Thermal Expansion. [Please help...I am so frustrated]

    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.)

    Simulation of Thermal Expansion. [Please help...I am so frustrated]

    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...

    Tracking movement of shafts in a housing deflection study

    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...

    What is the difference between Pro Mechanica and Creo simulate?

    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...

    Creo 2 simulate licensing

    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...

    Surface partitionning

    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...

    quantity of processors

    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...

    Creo 2 simulate licensing

    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...

    Creo 2 simulate licensing

    Creo Simulate Lite is available on all Creo licenses. Did you check the box (Simulate Lite) in the dialog for Model Setup?

    Contact Interface

    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"
