DOLFIN

CellSize(mesh) equivalent in c++

Asked by Patrick Riesen

dear all

I'm updating my code to the newest dolfin components (c++ code)

i used a defined function for the cell size

h = new CellSize(mesh);

in python, i noticed that this function still exists but what is the equivalent in c++ for the recent dolfin?

best regards,
patrick

sorry to bother again but
I could not find any c++ class for CellSize in the recent dolfin 1.2 release.
Was this renamed or removed?

How can I get a function for the cell sizes in my c++ code?

Or can/should I define it in a ufl-form?

happy easter,
patrick

Yes and yes. Look at

    demo/undocumented/dg-advection-diffusion/cpp/AdvectionDiffusion.ufl

If you want access from the C++ side, you could build a MeshFunction
using one of the functions in Cell.
