Dear all,
I have constructed this mesh in FEnics and I would like to compute the number of elements in the mesh (the mesh characteristics in general), I appreciate any help regarding this issue.
Here is my code:
from fenics import * from mshr import *
domain = Rectangle(Point(0.0,0.0),Point(1,0.5))
mesh = generate_mesh(domain, 50)
Hi,
You can check number of elements using following function
mesh.num_cells()
If you run your code in parallel, you need to sum size of all parts of mesh on each core, so you need to use
MPI.sum(MPI.comm_world, mesh.num_cells())
Similarly, for maximum and minimum elements size you may use
mesh.hmax()) mesh.hmin())
mesh.hmax())
mesh.hmin())
More about these and other mesh functions can be seen here.
mesh.num_cells() works
Thank youuu
