DESCRIPTION:[]\n\nPatients with muco-obstructive airway diseases\, such as 
 cystic fibrosis\, rely on daily therapies to help clear their airways. Hig
 h-frequency chest compression (HFCC) devices offer a home-based solution\,
  but variations in operating frequency raise concerns about treatment cons
 istency and effectiveness.\n\nIn this webinar\, Arife Uzundurukan\, a post
 doctoral fellow at Polytechnique Montreal\, will demonstrate how the COMSO
 L Multiphysics® software was used to develop a computed tomography-based 
 finite element model (CT-FEM) for predicting thoracic vibratory responses 
 across HFCC operating frequencies (5–100 Hz). The presentation will expl
 ore how lung behavior was simulated using Biot’s theory\, under both nor
 mal and pathological conditions.\n\nA detailed multi-organ thoracic model 
 — including the lungs\, ribcage\, trachea\, and soft tissues — was cre
 ated as a digital twin using a sequential workflow involving four differen
 t software platforms. The HFCC device itself was modeled as an acoustic pr
 essure source.\n\nResults reveal that the frequency response function (FRF
 ) peaks observed in the model align closely with findings from three indep
 endent experimental studies. Notably\, changes in alveolar radius signific
 antly influence wave velocity and energy density within the lungs\, withou
 t substantially altering the thorax’s overall FRF.\n\nAttend this live w
 ebinar to see how this study advances CT-FEM methodology for multi-organ s
 imulations and deepens our understanding of low-frequency thoracic resonan
 ce. You will also get a look at how COMSOL Multiphysics® is vital for bio
 medical and vibroacoustic modeling of human thorax digital twins.\n\nCo-sp
