[Gmsh] Mesh smoothing function

[SJ Lai]

Hello Christophe,

Thanks for the quick email last time, it really helped me.

My question this time is about the mesh smoothing function. There might be
some posts in the archives, but I have not yet been able to find it.

I was wondering if you can localise the mesh smoothing function over a
certain block rather than the whole mesh?

I've attached the geo file for my mesh, and as you can see, around the
aerofoil is a C Block  which needs to be smooth as possible. But between
volumes 1,2 and 3, the mesh needs to be as straight as possible. By
applying the Mesh Smoothing function, I've noticed that the C block gets
smoothed very well, but between volumes 1 2 and 3, you get sharp points at
where the mesh connects.

So could I apply the mesh smoothing only on the C block and not between
volumes 1,2, and 3 ?

Thanks very much

Jake
