One of the main issues you face as an analyst is the need to clean, defeature and midsurface geometry you import from CAD. Features like small holes, small steps and surfaces impact meshing speed and quality but can be irrelevant to engineering performance. You might also have to create midsurface geometry for thin-walled solid geometry so that you can create a shell mesh instead of a solid mesh. On average, for each design iteration, engineers spend an entire day or more just on geometry cleanup activities when using more traditional standalone CAE preprocessors. This wastes time that you could better spend doing real engineering. <\/p>\n\n\n\n
The source of the geometry data itself poses an additional challenge. CAE pre-processors usually do not support all CAD data equally. This results in data translation issues, lost or inaccurate geometry and ultimately in the need for even more manual geometry cleanup.<\/p>\n\n\n\n
