As a 2nd-year PhD researcher, I have been curious about the number of simulation-only PhD theses that exist in fields such as Engineering as well as unrelated fields as well. There is of course value in lab-testing, given how a simulation cannot always account for every boundary condition or factor. Usually, from my limited but growing experience, simulation, in the case of Additive Manufacturing and mechanical testing, is normally used as a validating tool; to help prove in a non-virtual environment what may be seen and tested in the lab, before any kind of scaling or future work is done using simulation (for cost-effectiveness and resource-saving etc.).
But in fields where in-situ testing is normally done, are there PhD theses that "Jump the gun" as it were, and go straight to simulation? Any information on this will be most appreciated given how, in some locations/countries where interaction and access to tools on campus and labs are minimal still due to Covid, improvisations must be made.
Ezekiel Yorke I believe you partly answered your question in the last sentence of the first paragraph-"for cost-effectiveness and resource-saving".
To add when conducting a simulation, you are actually performing numerical experiments and the results must be validated with experimental data and/or in feasible cases-results of analytical calculations.
