Thank you for viewing my question. I’m trying to extract interpolated values in a surface of 3D mesh to another 2D mesh with same surface area, but I have no idea how to achieve this. Following is a simple example: from dolfin import * #define mesh mesh1=UnitSquareMesh(10,10) mesh2=UnitCubeMesh(1…

Hi, dokken. Thanks for replying. But I’m still confused about extrating values in a certain facet after carefully reading the topic you suggested. Is there another typical example you can suggest for me? And also, where can I find the «parts of domain» you refered in that topic?

What I am suggesting is to use a restricted measure, i.e. ds = Measure("ds", domain=mesh1, subdomain_data=meshfunction_2D, subdomain_id=surface_id) see for instance: Poisson equation with multiple subdomains — DOLFIN documentation for more info regarding subdomains. Then you can simply do a restr…
