In HOPR, it is possible to read unstructured meshes with straight edged elements, and, if needed, use several curving methods to account for curved domain boundaries.

HOPR output: Curved surface and first layer of curved elements

To help the HOPR user to get familiar with these different features for external meshes three hands-on tutorials are provided.

External Meshes without Curved Boundaries

This tutorial shows how to read in externally generated unstructured and structured meshes with straight-edged elements.
