It’s been there since the start of the industry and still holds a dominant position for those simulating and analysing their products during development. I hear that ProE and ansys work well together though.Īnsys (stand alone) and Femap/nastran are the only two I would touch, and of those two feamap/nastran is much cheaper and easier to use. For those that are engaged in simulation in engineering, the name Ansys is one to note. External Geometry File > bracket.igs > Generate Figure 3-15 IGES import. Strand relies too heavily on external imports (or it did when I last looked)įEA that's bundled with 3D cad like cosmos in solidworks and ansys in Inventor are usually optimised for solid models whereas for boats you need shell and beam element models (havent looked at Inventor bundle but solidworks one was no good for boats). Design parameters appear as the CAD parameters in Analysis Modules if their.
Users should review the Ansys v15.0 Help system for information on this External Model feature. CAD Attribute Import The CAD Attribute Import capability can be used to import attribute information from CAD software, including motion loads For example, if a CAD system uses a supported kinematics program, the motion loads can be imported into Simulation for subsequent stress analyses If this feature is turned on, the prefix can be specified. Took about 2 weeks from start to finish.ĭue to the simplifications you can make in fea, more often than not cad data is not suitable for fea modelling.įorget strand, you need a geometry based modeller with its own set of drawing/modelling tools so you can make quick associative changes to your mesh. Workbench Mechanical at release 15.0 has a new External Model component system that can take a solid or shell finite element mesh from a CDB file, and generate a solid model with a mesh for use in Workbench Mechanical. I took the hull surface into it via iges (bottom, chine & sides only), used the split command to subdivide the surfaces at frame sections then built everything else in Femap as surfaces. ANSYS FLUENT allows you to import the following file formats: ABAQUS. I used to frequently model 50m cats and monos using nastran with Femap preprocessor, now called Femap with Nastran by UGS.
