    Please help with fixture advisor (elastic support)

    I suppose you could model the chain as a series of beams with appropriate gap elements. A kinematics solver would make easy work of it. TOP CSWP, BSSE www.engtran.com www.niswug.org www.linkedin.com/in/engineeringtransport Phenom IIx6 1100T = 8GB = FX1400 = XP64SP2 = SW2009SP3 "Node news is...

    Static simulation setup - question

    When you discuss loads and boundary conditions on this forum a picture is worth a thousand words. I would not assume body loads are applied unless I turned them on. Are you saying there are other loads in addition to gravity loads? TOP CSWP, BSSE www.engtran.com www.niswug.org...

    Simulation - static analysis fail

    When preparing a SolidWorks model for FEA it is always a good idea to use the TOOLS/CHECK functionality and find and remove gaps, small faces and edges and generally clean up the model by removing small features that have nothing to do with the FEA giving good answers.

    Static simulation setup - question

    Are you using body loads to simulate gravity? TOP CSWP, BSSE www.engtran.com www.niswug.org www.linkedin.com/in/engineeringtransport Phenom IIx6 1100T = 8GB = FX1400 = XP64SP2 = SW2009SP3 "Node news is good news."

    Contact Elements out of range?

    Sorry, it's been a while since I checked in here. I would look in the .out file to see which contact elements where giving trouble and then try to find them in the model. TOP CSWP, BSSE www.engtran.com www.niswug.org www.linkedin.com/in/engineeringtransport Phenom IIx6 1100T = 8GB = FX1400...

    SW Performance 2009 v 2012

    Sounds like you need to start a new thread for this. TOP CSWP, BSSE www.engtran.com www.niswug.org www.linkedin.com/in/engineeringtransport Phenom IIx6 1100T = 8GB = FX1400 = XP64SP2 = SW2009SP3 "Node news is good news."

    SW Performance 2009 v 2012

    I am not sure about recursive calls not working. My STAR benchmark runs on 2009 and it is all about recursion. It will run on 2004 on up. I have written elsewhere about the real cost of upgrading and ROI. I did my presentation on 4/17. One of my findings was that things like graphics cards...

    Best New Thing from the South Bend Tech Summit

    Professor Krishnan Suresh did a presentation on geometry optimization (PareTO) at the April 17th Tech Summit. The method he presented allows a designer to find the optimum geometry of a part very quickly. What he does amounts to doing numerous FEA runs starting with a block of material with...

    Principal Stress/Strain direction vector

    You might ask your VAR about documentation for the Simulation API. I'd be curious. TOP CSWP, BSSE www.engtran.com www.niswug.org www.linkedin.com/in/engineeringtransport Phenom IIx6 1100T = 8GB = FX1400 = XP64SP2 = SW2009SP3 "Node news is good news."

    MERGE 2 MACRO

    You want to combine both macros into one module and make sure the variable names are consistent. TOP CSWP, BSSE www.engtran.com www.niswug.org www.linkedin.com/in/engineeringtransport Phenom IIx6 1100T = 8GB = FX1400 = XP64SP2 = SW2009SP3 "Node news is good news."

    Principal Stress/Strain direction vector

    In Cosmos/M you may use the command language to query particular nodes and then do computations on their results. Unfortunately, the API for simulation is rather limited and I don't know of a way to do it there. TOP CSWP, BSSE www.engtran.com www.niswug.org...

    Print to specific printer per custom property

    Probably not, but you might look at fcsuper's macro collection and modify an existing macro. TOP CSWP, BSSE www.engtran.com www.niswug.org www.linkedin.com/in/engineeringtransport Phenom IIx6 1100T = 8GB = FX1400 = XP64SP2 = SW2009SP3 "Node news is good news."

    3D sketch points 'flip' 180¦ randomly

    You might turn on the option that shows the two sides of a plane using different colors. See if the planes flip between configurations. That might provide a clue.

    MERGE 2 MACRO

    Make one a subroutine in the other or make both subroutines ina third macro. Of course you then have to make sure that all global variables have the same name in both subs.

    Principal Stress/Strain direction vector

    Rosettes are better for actually finding the direction of principal strains. Adds one more channel. TOP CSWP, BSSE www.engtran.com www.niswug.org www.linkedin.com/in/engineeringtransport Phenom IIx6 1100T = 8GB = FX1400 = XP64SP2 = SW2009SP3 "Node news is good news."

    bolt preload simulation......please help

    Sounds like a text book homework problem. You could draw a diagram. That would help. If you are talking about separation, is this elasto-plastic? If you are talking about alternating loads, is this fatigue? TOP CSWP, BSSE www.engtran.com www.niswug.org...

    RUN MACRO ON EACH PART WITHIN ASSEMBLY

    And another thought, FILES/FIND REFERNCES will output a list of parts to the clipboard. Might be easier than using dir. TOP CSWP, BSSE www.engtran.com www.niswug.org www.linkedin.com/in/engineeringtransport Phenom IIx6 1100T = 8GB = FX1400 = XP64SP2 = SW2009SP3 "Node news is good news."

    RUN MACRO ON EACH PART WITHIN ASSEMBLY

    The simplest way is to dump: dir *.sldprt > tempfile.lis and then read that file into your macro using each line as a filename. Of course you will have to get dir to output just filenames and extensions and perhaps clean up the file in an editor a bit. TOP CSWP, BSSE www.engtran.com...

    SW Performance 2009 v 2012

    I am working on a performance presentation and I ran across this interesting conundrum. I ran these benchmarks in 2009 and am doing so again in 2012 on a much faster machine. The rebuild times don't improve as much as the Punch Holder benchmark would suggest they should. 600s vs 48s Does...
