No good:( I do not understand index:( Therefore I cannot solute this:( Can you do one example? For r components? Kamil

Thank you very much:) Now I try to understand this:)

At page http://mathworld.wolfram.com/CylindricalCoordinates.html formulas (47-49). If I add this I will obtain derivative for r component in cylindrical coordinate( [v*delatV]r) I have to obtain the same for Laplacian equation for each components ( [delta2V]r) I have this solution but I do not...

Yes but I have to solution for each components. I have to have laplacian for r,teta and z seperately. Formulas (91 -92) are showed finaly equation. Kamil

Thanks for answered dextercioby. I am based on this article: http://mathworld.wolfram.com/CylindricalCoordinates.html Please you look equation (46 – 55). I would like to do for Laplacian. If you know how please write me.

Hello! I am trying t solution Navier-Stokes equation and I cannot find something about Laplacian. I would like to solution Laplace’a equation for each component.I am trying to transform cylindrical coordinate. I would like to search equation for covariant derivative. For divergence of a...
