Export as colored STL

Is there a way to export onshape models to a collered STL so it is easy to use as starting point for openFOAM CFD?
Can you do this within onshape or is there an app that can do this?

Thanks in advance

    We can export Onshape model to STL but not sure what exactly collered STL means. But anyways for performing operations in STL file there is one app in App Store known as STL workbench. Here is the link of the thread for details.

    Simscale uses Openfoam as a CFD solver, and it has a direct link to Onshape, so you don't need to use an STL file to import into snappymesh. It's very quick and easy.

    Thanks for the replies. I know about Simscale, but I want to be able to use self developed solvers, which is not possible with Simscale.

    I will have a look at the STL workbench.

    You could also look into InStep... the FE version allows you to take an Onshape document and download it directly into InStep. In the FE version, you can then save the file as a NASTRAN surface mesh... the mesh is a 1:1 of the STL tesselation, so changing the import parameters will allow you to modify this to some extent (kind of like a poor-man's surface mesher). This is a bit of an advanced topic, so I suggest you give it a try using the free version and contact support ([email protected]) if you run into issues (after reading the help files online). Feel free to post questions/solutions here too though ...
