Hi everyone,

I was wondering if there are tools, other than BlueKenue, to mesh very large models for use with T2D (more than 12M elements)? BlueKenue is too slow.
Let me explain:
I am dealing with urban ponding areas in a large city somewhere in the middle-east where my mesh size varies between 1m to 50m (Some internal roads are 6m width) and the area is simply huge. I would like to generate a good quality mesh but in reasonable time (less than 2 days for example) on a HP Z640 series workstation. Eventually generate the mesh using all available cores (in parallel quoi

)

Thank you,
Aissa

However I didn't try Basemesh for such large meshes. Triangle itself should be fast since it is famous especially for that. Best regards, Clemens
