Want to solve Poisson Eqn. on aHigh-order VTK .vtu mesh

General

Greetings
I am very new to the FeniCs project and do not even know what it can’t do.
I have a .vtu file which consists of 3-D unstructured mesh (high-order VTK hex & prisms) and fields of several variables on it. I want to read it on FeNiCs and solve a certain Poisson equation, the homogeneous term being a function of the some available variable fields. Is it possible to read in high-order VTK and solve the equation keeping the high-order accuracy?

Thanks for the response,
Kenan

There is currently no support for mixed higher order meshes in the FEniCS project.
This is being worked on in:

Single celltype geometries of higher order can be used in DOLFINx.
