In the field of Mechanical Engineering, when doing a PhD in a University but in partnership with a company, at some universities, an agreement is signed between the company and the university (or Laboratory) in which the company remains the owner of all files provided (e.g. geometries, meshes) as well as the results produced, but allows for publication of most of the results. The line drawn between what its supposed to be published and what remains strictly confidential is hard to draw and often depends on the company as well as the topic.
Usually, in order to preserve this confidentiality, researchers scale the figures to unknown values and do not provide geometries or mesh/material properties for example. I was wondering if this common practice in scientific publication can be applied when writing a PhD Thesis. Basically, are all results presented in a thesis supposed to be public and more importantly, is an independent/external researcher supposed to be able to reproduce all of the results ?
