PDF REPORT

The simulation result is provided in a PDF report and in a interactive 3D viewer. Its objective is to read the results of a case in an agile and detailed manner.

A copy is obtained from the detail of a completed case, which will always be available from the platform for visualization or download. Two studies are generated representing airflow: INSPIRATION and EXPIRATION.

This report provides quantitative information on the functionality of airflow in the nasal cavity of each patient. This information has to be taken as a support to the diagnosis that has to be substantiated in a computation of data and methodologies to give a better medical service to patients.

HOW TO ACCESS THE PDF REPORT?

RESULTS OF THE STUDY

PDF report is composed of the following data.

MESH QUALITY

Details the quality data of the obtained geometry to assess the reliability of the simulation result.

DESCRIPTIVE STATISTICS

The measurement values of the structure are detailed, like the Perimeter (cm) of the two entries (nostrils), the way out to the lower respiratory tract (nasopharynx).

Area (cm2) of the entries, outputs and the complete nasal cavity, as well as its total Volume (cm3).

ACOUSTIC RHINOMETRY

A graph similar to an Acoustic Rinometry is represented, but not equivalent. More specifically, the area curves associated with the coronal sections of the nasal cavity are represented. The detected contacts between the left and right cavities are also represented.

RESIDUALS CONVERGENCE

In this type of simulations the results they can be considered as an error indicator. All residuals is represented in a line. The results must be less than 0.001 at the end of the simulation. Otherwise, the simulation has not converged, so the results should not be considered valid.

FLOW FIELDS CONVERGENCE

The flowrate an velocity they can also be tracked to check the convergence. The line represented in the graph must have a constant value at the end of the simulation.

SIMULATION RESULTS

PDF report contains the following results of the simulation.

NUMERICAL VALUES OF FLOW VARIABLES

The maximum and minimum values of the variables of Velocity magnitude (m/s), Pressure (Pa) and Temperature (C).

NASAL RESISTANCE

he measurement of Nasal resistance is detailed [Pa • s / cm3] in the total computation.

FLOW RATE PARTITIONING

The amount of fluid circulating through the nasal cavity is detailed per unit of time (l/m).

VARIABLES. PRESET CUTS

PDF report contains the following information.

PRESSURE DISTRIBUTION OVER THE WALLS

It is represented, on the geometry of the anatomy, a colored mask that indicates the pressure values in the walls of the nasal cavity.

WALL SHEAR STRESS DISTRIBUTION OVER THE WALLS (WSS)

It is represented, on the geometry of the anatomy the stress areas by the friction of the flow in the walls of the nasal cavity.

STREAMLINES

This section shows the airflow current lines of the two sides in the nasal cavity representing speed values by means of “streamlines”.

AXIAL, SAGITTAL AND CORONAL CUTS

Are detailed, in various pre-established cuts of the three axes, the values of the following variables: Temperature (C), Pressure (Pa) and Velocity (m/s). The Temperature profile is represented in ºC, you can observe the temperature in the different anatomical areas. The Pressure profile is represented in Pascals, you can observe the pressure of the airflow in the different anatomical areas of the nasal cavity. And finally the Velocity profile that is represented in meters per second, the speed of airflow in the different anatomical areas of the nasal cavity can be observed.
