Simulation results: effects of Chiari type 1 malformation on cerebrospinal fluid dynamics during arterial pulsations and coughing

The folder contains the simulation results corresponding to the computational fluid dynamics study: Effects of Chiari type 1 malformation on cerebrospinal fluid dynamics during arterial pulsations and coughing

Data is organized in the following way with files in .csv and .xlsx format

Cropped model:

output_*: flow time in seconds, pressure in the fourth ventricle (Pv), outflow in m³/s or kg/s, and pressure at plane in spinal SAS (Psas) for physical herniations and herniations created by porous zones

Full model

arterial_pulsations: data with all boundary conditions (arterial) except from cough

arterial_pulsations_and_cough: data with all boundary conditions (arterial) including cough

file content:

*_boundary_data: time step number, number of coupling iterations necessary per time step, flow time (s), pressure (P) and flow (Q) at outlets with interstitium (1), spinal (2), lymphatic (3) and arachnoid villi (4), first element of Jacobian (J11), flow residual, value of perturbation (dP) in Pa, converged?: 1 when converged, 0 when not, perturbation parameter, number of times the perturbation value needed to be reduced.

*_flow: flow time in seconds, volumetric flow through aqueduct, and spinal SAS

*_pressure_data: flow time in seconds, relative pressure compared to interstitium outlet at the fourth ventricle (v4), the spinal SAS (sas) and the lateral ventricle (lv)
