Software Integration What is Femap? Why use it here? Powerful mesh-centric FE pre- and post-processing

Mars Rover Curiosity High performance simulation that significantly Courtesy of NASA JPL reduces physical testing and speeds time to market CAD-independent finite element modeling Proven, powerful modeling and analysis capabilities that solve the toughest engineering problems The best Nastran pre- and postprocessor on the market.  NX Nastran is great for structural analysis of lifting loads, shock loads and DDAM, structural dynamics James Webb Space Telescope Femap/NXN are currently in use at several shipyards Courtesy of NASA Goddard Excellent application programming interface (API) for task automation. No changes to core Femap code needed. ATA has developed several commercial software products that leverage the Femap API Our Software Services - NSRP Automation for faster structural analysis 2017 Panel Project: CAD to FEA Automation Partnered with Ingalls and SSI Automated extraction of ship data (geometry, materials, stock data, equipment mass and inertia) from ShipConstructor Automated creation of mesh-ready geometry and properties in Femap to expedite finite element modeling 2018 Research Announcement: LiftShip Partnering with SSI, expanding CAD to FEA panel project work to expedite FEA for ship lift configurations LiftShip Program Status Summary Import from ShipConstructor to Femap Complete:  Flat plates and stiffeners – imported as surfaces on moldlines  Equipment – imported as lumped masses at CG  HVAC & piping – lumped masses at CG & path curves  ID info – plate stock, material info, equipment names & mass become properties and are assigned to geometry Remaining challenges:  Lift-specific hardware  Curved & corrugated plates  Bridging CAD needs for designers vs. analysts Geometry Prep for Meshing Complete:  Intersection of contacting surfaces to assume welded connection  Trimming or extension of intersected surfaces SSI Assembly Example 55 seconds to import and prep geometry from PublisherLT

Femap

ShipConstructor Catching “Leaky” Geometry Bridging the divide between designers & analysts

ATA uses SC construction geometry directly (no export/import of STEP) SC allows designers to create plate geometry with small inaccuracies Open boundaries on faces Gaps between parts These inaccuracies can result in invalid geometry in Femap during import Invalid geometry is flagged and grouped for correction Taming Curved Plates Ongoing work to determine the best solution
