Thank you Luca for the response. I see that manifolds will not work in the way I was expecting. I want to map a fixed Cartesian mesh to some other domain, e.g., as in the work of Thomas Wick. So I dont want to modify the Cartesian mesh, as it is supposed to describe the reference domain. I am

I think you are essentially trying to achieve what step-53 does. It’s unclear to me what you mean by “I want the grid to be Cartesian”. Topologically? Or you literally want just one layer of elements to follow your manifold description? In this last case, you should not attach a manifold right a

Dear all Suppose I have a unit square and I want to map the top side y = 1 to y = 1 + 0.1 * sin(2*pi*x) I want the grid to be still Cartesian but attach a manifold to top side. This does not seem to be possible with Manifold/ChartManifold/FunctionManifold etc., is this correct ? I can use
