    The Mechanical Engineer - Shape Shifter
    I think CEOs, HR directors, and even college graduates could all be a little confused as to what is expected when it comes to what we mean by a "Mechanical Engineer".

    Equivalencing Nodes
    I set out to create a 3D hex model using 2-1/2D extrusion in APEX and run Random Vibration from within Patran. My model was a machined aluminum component. My strategy was to create the base surfaces in the x-y plane and then "extrude" them into the z-direction of various heights to create a an aluminum component with RF "trenches". Once the 3D geometry was in place, it should have been trivial to mesh with hex elements using the 2.5D mesher. Or so I thought ... I built the surfaces as shown

    Surface with a hole
    To create a hole in a planar surface would seem trivial for Apex. However, it took me quite a while to figure it out and so I thought it was worthy of note. I had imported a bunch of IGES lines that defined the outer perimeter of the surface and two 180 degree arcs for the hole in the middle. I was really trying to avoid the old "Patran" approach of breaking curves to make a bunch of 4-sided polygons. I tried using the Drag Edge tool but there was a not a one-to-one matchup of curve segments on

    MSC One License Installation
    As an MSC Apex Elite Agent, my company, DHL Consulting, is entitled to an MSC One license to be able to run MSC/Apex for demonstration purposes. About three weeks ago, I submitted a request form to MSC. The process is very streamlined and a couple days later I received by license.dat file. However, after downloading and installing the software along with the MSC Licensing Utility, it shows you what your HostID is during installation. It was then I quickly realized that my HostID had changed due

    My first Apex model
    I am, like most finite element analysts out there, new to MSC/Apex. I'm working through the process of coming up to speed and will document my findings along the way. This will help you, should you be evaluating the Apex software. Although I am an MSC Elite Channel Partner for the Apex product, I consider myself independent from MSC and will document my honest assessment of the Apex learning experience. Background Before embarking to create a model from scratch, I have spent perhaps 15 hours to
