Medical/electrical/mechanical engineering

I have existing equation-based and FEM-based models for the physical, electric, magnetic, and thermal activity of the human head. I also have the documentation explaining the model. The model is relatively simple and based on very basic shapes. The existing model just needs to be validated and updated to fit the desired modeling scenarios. All in all there will be about 5 versions of the base model, and then combinations of those 5 variants.
