Human file export

[Ravi Kumar ae20d006]

I am trying to export a human model made in openVSP in almost every format and want to import and do the grid generation but either the file exporting is having problem or the database is not changing to a form which can be used for grid generation ... 

Can some one please help ..

Thank you for the help

The Human in OpenVSP is an unstructured triangle mesh -- not a Bezier surface.  Consequently, only the tri mesh export formats will work.

This means STL, MSH, and OBJ are your best bets for working with other software.

I tried exporting the Human model in the formats you mentioned and bringing it into Pointwise, but I feel like I’m missing something—though I’m not sure what exactly. I also tried the route of importing it into SolidWorks first and then exporting it to Pointwise for the surface and outer-body grid, but again it seems I’m doing something wrong.

I’d really appreciate it if you could list the key steps or any crucial checks in the export/import process that I might be overlooking while getting the model into Pointwise.

Let's take a step back.

Why do you want to perform grid generation steps on the statistical human analog?  That component is generally intended for cabin sizing, clearances, range of motion, or weight estimates, to name a few applications.  CFD or other processes that would required grid generation are not among the uses envisioned for this part.  What are you trying to do?

The Human component is not a Bezier surface, as Rob already stated.  So you have no mesh refinement control in OpenVSP.  Exporting the human mesh as an STL or other triangulated format will not typically serve to increase the resolution because any grid tool will likely just add resolution on the patches between the points.  You won't get a smoother surface.

If you are trying to run CFD or FEA on the Human mesh, my suggestion is: Don't.  Your results will be meaningless even if you get it to work.
