Hi Caen, Converting a .stl -> .step for use of FEA analysis is a really perverse idea ;) low order geometry -> higher order geometry -> lower order geometry is just increasing the pain / complexity rather than reducing it. Also; in CAD a few nurbs patches can easily take up thousands of triangles to be described accurately!
What you should look into is re-meshing your STL file into something that your solver can grok. There are pre-processors ( patran ) that will do this for you. -jelle > Hi Thiago & Thomas, > > Thanks for your replies. > > Acturally I got that 'my.iges' file.
