When you have a big target but the deformation of concentrated in a small portion, it is recommended to do gradual mesh. You can remesh the whole thing or use adaptive mesh, which both are computationally expensive. So, in this video, I will share with you how to do this type of gradual mesh using Prepost! Of course, we can use ANSYS or HYPERMESH but not all have access them. But LS-Prepost is free and you just need internet connection to download it!
