Meshing problem

[Anonymous]

I'm working on modifying a carbon fiber rotor for a quadcopter. I've made the model of our part in inventor, but when I go to stress test it, it gives me a mesh failure notification. If it's something simple then that's great, I'm teaching myself the program as I go along and this is one of the only issues that I haven't been able to address myself.

Is carbon fiber an isotropic material?

Have you installed the latest Service Pack and Update for your version of Inventor?

The geometry appears to be poorly modeled - with underdefined sketches and little itty bitty steps that don't make logical sense?

I got lost at Extrusion 8-11, shouldn't that have been modeled as planar faced box to start with rather than be part of the Loft feature?

How will this feature be manufactured?  Is this what you really really want?

The loft created divots in areas that I wanted to be straight so I tried to fix it with the extrusions. This part is also not being manufactured, it is an attempt at recreating a real life product. We have the blade in a lab and we are attempting to create it in inventor so that we can run stress tests on our modifications. The blade that we have is carbon fiber, I chose that material in an effort to have a more accurate stress test results. Was that necessary? I'm unaware if we have the neweset Service Pack and Update as we are using the license that our school provided to students.
