Hello everyone !
I just want to ask a question:
Can we discretize initial mesh in quadrilateral elements in FeniCS ? If yes, Please share some details how can we do.
Thanks
Ayush
In DOLFINx there is support for quadrilateral and hexahedral meshes.
See for instance: Test problem 2: Flow past a cylinder (DFG 2D-3 benchmark) — FEniCSx tutorial
that uses second order quadrilateral elements to define the geometry.
Thank you sir for the response
Can you provide some reference in FeniCS because I am not familiar with FeniCSx ?
In legacy fenics, only built in meshes, such as the unit square, support quadrilateral elements. This is one of the many improvements in DOLFINx over legacy DOLFIN
