Finite element method: How to calculate jacobi matrix in cylindrical coordinate system

HI

How do we write jacobian matrix in cylindrical coordinate system for 2D and 3D domain.

2D domain is given in image

[Torsten]

Which Jacobian matrix ? The Jacobian of the mapping from cartesian to cylindrical coordiantes ?

[jeewan atwal]

no, the jacobian that is used to map locall shape function derivative to global shape function derivative

I wonder if you found the solution!
