Before revision:  Thus, topology and quality of the original mesh are preserved, enabling application of POD-based reduced order modeling techniques, and avoiding the necessity to additional meshing steps  .
After revision:  Thus, topology and quality of the original mesh are preserved, enabling application of POD-based reduced order modeling techniques, and avoiding the necessity to additional meshing steps . Model order reduction is performed coupling POD and Gaussian process regression (GPR) in a data-driven fashion .
