The goal of this chapter is to demonstrate how one can go from a surface triangulation of the brain to modeling cerebrospinal fluid (CSF) flow. Specifically, the model will include the subarachnoid space, a ventricular system, and the CSF produced by the choroid plexus in the ventricles. The CSF is modeled to adhere to the Stokes equations, which in turn are solved with FEniCS, a finite element framework using an iterative solver. The computed velocity field corresponds well with current experimental and computational studies.

摘要

The goal of this chapter is to demonstrate how one can go from a surface triangulation of the brain to modeling cerebrospinal fluid (CSF) flow. Specifically, the model will include the subarachnoid space, a ventricular system, and the CSF produced by the choroid plexus in the ventricles. The CSF is modeled to adhere to the Stokes equations, which in turn are solved with FEniCS, a finite element framework using an iterative solver. The computed velocity field corresponds well with current experimental and computational studies.
