[Gmsh] nodal coordinates

[Manav Bhatia]

Hi,

    Could I also add to my earlier question the following: Is it also  
possible to get access to the derivatives of the local coordinates  
with respect to the global ones? This might be a tricky issue for  
curved geometries, since tensorial components might be used, but it  
will be helpful.
    I have the following problem: If I know the sensitivity of the  
elementary points with respect to some parameter alpha, then I would  
like to calculate the sensitivity of the global nodal coordinates with  
respect to this parameter.

    Thanks in advance for your response.

Regards,
Manav
