Implementing amplified MRI in a computational fluid dynamics model of the cerebrospinal fluid

This folder respository contains files to implement measured amplified MRI motion into a CFD model. The files should be imported in FLUENT (Ansys Inc.) in the following order:

setup_case.jou: journal file containing the commands to setup the CFD model in FLUENT (Ansys Inc.). This file also compiles and loads the UDF mesh_motion_all_v2023.c. The UDF is directly based on the code provided in the Github respiratory (CoCoNuT). A define-on-demand function should then be executed to export the unique node ids from FLUENT. 

Run the Python file link_node_id_spline_interpolation.ipynb which returns .dat files for the different timesteps. 

run_motion.jou: journal file that reads the .dat files generated in step 2 and applies the mesh motion in the CFD model.
