    mysterious file size growth - caused by2 many changes?

    brad3378, May be the file size increased due to the grow of the information retained in the part's 'history tree' after each modification. If you do not need those info, you can use 'extract surfaces' function to duplicate your part to an orphan part, and delete the original part to reduce file...

    Crack progation

    jazzyg, Only the 'crack interface' that you created will 'open up', but will not propagate through other elements. However, you can examine the tendency of further propagation of the crack by the means of strain energy release rate(G) with various technique e.g. virtual crack closure...

    Absolute vs. Relative design?

    whether become a absolutist or relativist would depend on the field that we're working on.... If you are dealing with rather simple application(for example design metal part to work below yield point), or in an academic institution where you may have the luxury of time & budget to characterise...

    Refrence Temperature in Ideas

    tipsnitin, Are you performing a pure thermal analysis, or thermal-mechanical analysis (i.e. CTE -stress)? It's sound like you are doing a thermal-mechanical analysis. 1. You can define the reference temp. & ambient temp. in the Boundary conditions task> set> temperature. 2. The default ref...

    Crack progation

    jazzyg, I apply the following steps to model a separate-able interface(crack!): 1. create additional nodes (overlap on the existing nodes)along the crack-line. 2. delete the ELEMENTS along the crack-line (for a 2D crack model, i.e. elements on both sides of the crack-line).Note that all the...

    problem running IDEAS NX 10m3 in windows xp

    feadude, Usually how Flexlm work is: detect ethernet card hostid -> match with license file -> release license. I'm not sure whether Ideas license would work without an registered ethernet card. Did the Ideas-support mention on this when they provide the license file?

    problem running IDEAS NX 10m3 in windows xp

    feadude, Do you have an ethernet card on your PC? The license file is generated for ethernet card with system-ID 00b0d0e965e5, while your system ID is 000000000000. Look like you don't have an ethernet card, or with an ethernet card with different system ID.

    Material data database software

    check on www.campusplastics.com. It's pretty useful & most of the Europe material supplier provide their products in details there!

    problem running IDEAS NX 10m3 in windows xp

    feadude, I can read the license file correctly at the license server. The following items may help to check for the problems: 1. are you selected 'full installation' during setup. 2. in the Flexlm Manager- setup tab, is the lmgd.exe, license file, log file path correctly directed to the related...

    problem running IDEAS NX 10m3 in windows xp

    feadude, Can you check whether you have the FlexLm Manager installed as well on your home PC? I have the FlexLm Manager installed although my workstation is not the license server. You can check for the 'FlexLm Manager' icon in the control panel. Open the 'FlexLm Manager' and click 'stop' then...

    problem running IDEAS NX 10m3 in windows xp

    I encountered this before. I restart the FlexLM in the licence server and it solved. Good luck to you.

    Creating FEM from assembly

    Hi, I don't think the constraint in CAD model can be automatically translated into FE constraint, although Ideas has good CAD-CAE interface. In your case, you need to define interface element (i.e. spring element) between the 2 blocks to represent the joint. BTW, what are you evaluating? the...

    Wireframe/curve selection problems

    martin, have you try to use the filter function to help your selection (i.e. right click > select 'filter' > pick only curves)?

    Nonlinear statics on a previously deformed model

    Peter, You can define dynamic loading(eg. change vs time) in non-linear analisys. If there is change in geometry that would require the stiffness matrix to be reformed in particular load step, you can activate the 'stress stiffneing' option. If not mistaken, The restart function also allow you...
