Curved elements generation

Hi all,

Quick question: how did the authors create “quadratically curved elements” for the cylinder and T106D LPT blade case in the following papers?

[1] B. C. Vermeire, F. D. Witherden, and P. E. Vincent, “On the utility of GPU accelerated high-order methods for unsteady flow simulations: A comparison with industry-standard tools,” J. Comput. Phys., vol. 334, 2017.

[2] P. Vincent, F. Witherden, B. Vermeire, J. S. Park, and A. Iyer, “Towards Green Aviation with Python at Petascale,” Int. Conf. High Perform. Comput. Networking, Storage Anal. SC, no. November, pp. 1–11, 2017.

Thank you for your time.

Cheers,
Vishal

Hi Vishal,

In Gmsh after building the mesh you just click the “set order 2” option and it will convert the elements from linear to quadratic. After this you need to make sure none of the curved elements are self intersecting by inspecting the mesh.

Thanks,
