  abstract = {Established a posteriori mesh curving techniques often rely on an accurate CAD parametrisation of the underlying mesh objects which may not always be available. To deal with such cases, we propose a method for reconstructing the missing information between the mesh and the CAD geometry when importing an arbitrarily sourced straight- sided mesh. The reconstruction is followed by curving methods for order elevation, projections and, subsequently, optimisation. Lastly, mesh modification techniques are used to achieve the desired mesh resolution and quality. We illustrate the steps of the proposed workflow through a simple geometry and a complex automotive geometry.}

The conference version of our work on curving imported meshes. Where the CAD parametrisation an imported straight-sided mesh would need is missing, the workflow reconstructs it, then elevates, projects and optimises the mesh before refining it to the resolution wanted. Shown on a simple geometry and on a complex automotive one.
