Immersed mesh - STL surface intersection tool
 

Hi all,


I will be working on a project of which I have given a brief description:


The work is to enable visualization of data for immersed boundaries in Tecplot. Essentially, there is a refined hex mesh with a STL surface mesh (triangular elements to describe the surface geometry). The hex mesh cells lie both inside and outside of the geometry. Hence, some cells are cut by the STL mesh. The objective is to detect these cells, then detect the points of intersection and convert these hex cells into polyhedral cells so that they can be visualized in Tecplot.

I thought of using the snappyHexMesh tool from open-foam, but I realized that it morphs the cells around the geometry rather than computing intersection points.

So what I want to know is if you know any tool in OpenFoam (since the code is opensource) or otherwise that can do this?


Thank you

Arvind
