renumberMesh increases max aspect ratio
Hi all,

Sometimes I see renumberMesh increasing max aspect ratio, max skewness, max non - orthogonality.

I find this weird because it is only supposed to reorder the nodes, not to move them.

I must say that it happens when large aspect ratio (around 20) exists before renumbering.

Did anyone experiment such a behavior ? Or must I pay more attention to my initial mesh ?

Might be a write truncation problem. Increase the write precision in your controlDict or even better set the writeFormat to binary.

Thanks Mattijs ! You were right. I turned back write precision to 6 and renumberMesh works well.
