See how to generate a mesh from scanned data via two different workflows. For both examples, the data file is imported in an Interpolation function.

In the first workflow, the data is applied on a Grid dataset and a Filter dataset is used to filter out the data to represent the femur. This generates a surface mesh that is smoothened using two Free Triangular operations. Two screws are added to show how to add extra computational domains to the mesh. Explore this workflow with the MPH-file titled "mesh from scanned data remeshing as smoothing".

In the second workflow, a regular block domain is created on which the femur data is applied. Solve the Helmholtz equation to smooth the data to get a smooth surface mesh of the femur. The surface mesh of the femur still needs to be remeshed, but this time only to improve the quality of the mesh elements. Explore this workflow with the MPH-file titled "mesh from scanned data helmholtz".

A more detailed description of this model can be found in the blog post "Generating a Simulation Mesh of a Femur From 3D Data".
