Hello, my name is Diego, I am the owner of Accuracy FEA, we are dedicated to research and development in projects of engineering.
We perform simulations with Comsol and Ansys, as well as numerical analysis with MATLAB.
I suggest you check my profile on Freelancer about the FEA projects. I am a freelancer preferred and certified, all comments are 5 stars.
I propose to turn that geometry into facets, then vectorize the faces and leave the region that you want to modify in order to do it parametrically and link it to the ansys workbench, in that way you could iterate in a parameter that changes the size of the model.
I would like to be able to work on your project, I hope your contact. thank you very much.
