Issues with triple line smoothing and segmentation faults

[bbbates1]

Hi Carl,
I am working on using this code to prepare a microstructure for meshing. I generated a voxel data set in dream3d and used this code to generate a smooth surface mesh for meshing. I exported the output as an Abaqus file and then intended to re-mesh it in Cubit. Some of the triple lines in the smoothed surfaces ended up very jagged, preventing a high quality mesh from being created. Here is an example of a jagged triple line:

Modifying the settings of both the smoothing and coarsening stages did not seem to make an appreciable difference in this. I also tried generating a new microstructure in case the issues were with the geometry of the data set I was using. This always resulted in segmentation faults about halfway through the coarsening stage of the smoothing. Do you know why this might be happening or how I can improve the quality of the triple lines?
Thank you,
Ben

Hi! I am on vacation right now and do not have access to a computer, but I can look into it when I get home. In the meantime, can you send the file you try to smooth? That will make thing easier 😁 Carl Den tors 22 juli 2021 20:43bbbates1 ***@***.***> skrev:

Thank you for the fast reply, I would be happy to provide the files I am using. I saw your email address as sandstrom.carl@gmail.com in a different post on this page, is that a good email to use?
