You have to be careful when importing 'lines' from one software into any FEA. Even if the 'translation' works using either IGES or DXF. You can have either one point or literally millions of points per curve. This just means you have to do a lot of 'editing' of the data inside the FE program. Because to create the FE model requires connectivity, ie lines that all join together and the intersections being real intersections to model structure. I gave up importing lines from other software years ago and now just model inside the FE program. Much quicker and easier and i can control where the line breaks are for ease of creating surfaces or extruding volumes etc.

Since without this, the mesh is a mess!!! I used to frequently model 50m cats and monos using nastran with Femap preprocessor, now called Femap with Nastran by UGS. 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. I then just automeshed the surfaces. Took about 2 weeks from start to finish.

Due to the simplifications you can make in fea, more often than not cad data is not suitable for fea modelling. Forget 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. Antonio Jose Sonata Pdf Files there.

Strand relies too heavily on external imports (or it did when I last looked) FEA 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). I hear that ProE and ansys work well together though. Ansys (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.
