    Nastran SOL number option in .dat file

    In the Analysis Set Manager, when you set up your NASTRAN run, under "NASTRAN Executive and Solution Options", you can specify a "Solution Overrride", and manually enter the 103. There is no automated way to have the NASTRAN SOL Name always replaced with the SOL Number. Mark.

    Simple API for View Options

    Since you said you were new to the API, I wrote this one for you, you can edit this to test and see if node labels are already on, and if so, turn them off and make it a quick toggle. I added comments to each line to hopefully help with your FEMAP API learning - Sub Main ' Connect to the...

    NX Advanced Simulation - Beam deflection

    The textbook formula you have is for Pinned-Pinned Beam. In the NX model, you have one end with TX, TY, TZ and RX constrained, basically pinned in the XZ plane, which is fine. At the other end you have TY and TZ constrained, but TX is free, therefore your beam is free to slide at this end in...

    Is there a command to see which groups an entity is in?

    On the FEMAP "Select" Toolbar, there's an option on the second icon to toggle on/off "Layers/Groups in Tooltips". If you toggle this on, when you are using the Select Toolbar to choose elements, nodes, etc. and you have the tooltips on, you will see Group and Layer information in the tooltip...

    Anyone attending Siemens PLM Connect next week?

    Andy Haines and Patrick Kriengsiri from the FEMAP team will be at PLM Connection. There's a FEMAP workstation they'll be manning. Please stop by and say hello!

    Results not matching in structural analysis - For Full model analysis and a portion of the model.

    I'm the development manager for FEMAP and can only control and comment on what goes into FEMAP. If you send me your two NASTRAN input files, myself, or one of my NASTRAN guys might be able to figure out what's causing the differences. sherman dot mark at siemens dot com

    Results not matching in structural analysis - For Full model analysis and a portion of the model.

    Applying displacements to a cut mesh can often lead to stress peaks. The enforced displacements, if not truly smooth and continuous will introduce some significant stress risers. From the FEMAP side, we've recently added a Global/Local modeling tool that helps you bring forces from the larger...

    Error: System not authorized for geometry modeling engines

    Go to File - Preferences, and click the Geometry/Model tab. Make sure your geometry engine is set to Parasolid. This is a hold-over from when FEMAP supported both ACIS and Parasolid. Since most users just set it to Parsolid and forget it, it really doesn't get used much any more. There is a...

    common error on Femap: negatives pivots

    Please post your FEMAP model, we'll figure it out - Mark.

    Beam Cross Section Stress Control not working with "Hole to hole fasteners"

    I just tried this in v11.0.1 and it works for me. The single requirement for View, Advanced Post, Beam Cross Section is that one has recovered the elemental forces from the finite element solve. If you'd like to send me your model where this is not working, I'd be glad to figure it out -...

    Optimization options

    In addition, the contract with the optimization technology provider has since been voided. One cannot currently purchase the topoolgy optimization module. The NX Nastran team is working on a replacement that should be available in a release or two. Mark Sherman Manager - FEMAP Product Development

    Difference Between "Stitch" and "Non-Manifold Add" in Solid Geometry Creation

    Non-Manifold Add is being updated for FEMAP 11.1. We worked with the Parasolid team and non-manifold add is much more "tolerant" than it was in the past. Similar to how stitching can use a tolerance to bring edges together, non-manifold add will be able to do so in the next release. If anyone...

    create superelement

    In v10.3.1 it's a manual process to make this happen. In v11, we added support in the FEMAP GUI to create external superelements and also to incorporate external superelements in other models.

    Meshing

    When meshing a surface, press the "More Options" button in the "Automesh Surfaces" dialog box. In hear, there's a parameter for meshing called "Cut Quads with Angle Deviations Above", set to 60.0. This will tell FEMAP to split any quads who have a corner angle less than 30 or greater than 150...

    Running Analysis in NEiNastran using API script automatically

    If you create and environment variable NENAST_EXE=.... pointing to the NE Nastran executable, am.Analyze should then launch and run NE Nastran for you. Mark.
