Problem about "sfepy.mesh.mesh_tools.smooth_mesh" module for large datasets

Hi everyone,

I have a problem about "sfepy.mesh.mesh_tools.smooth_mesh" module, when it comes to large data size, the running time is very long. I have a model with about 300,000 cells, now already taken more than 10 hours, but still not finished yet.

So I wonder, if anyone has experience know the some tricks to make it running faster?

Thanks for your time. BR, Xiaogai
