The design of blood processing and blood handling devices has proven to be a challenging task because it is of utmost importance to prevent hemolysis (damage of red blood cells) and thrombosis (clotting of blood). With its state-of-the-art meshing technologies, comprehensive range of physics models and easy-to-use environment, STAR-CCM+ can be used to predict blood flow and prototype device designs before time-consuming clinical tests need to be carried out. From assessing the efficiency of heart valves to designing blood pumps to evaluating the blood flow inside an aneurism, using STAR-CCM+ results in innovation and reduced time-to-market.
The complex FSI problems in biomedical device industry are driven by highly compliant vessels and membranes that are structurally impacted by medical devices and blood flow. To address this, STAR-CCM+ has a direct link to Abaqus finite element analysis through a co-simulation API developed by SIMULIA, delivering a fully coupled, implicit, two-way FSI and providing automation, efficiency and solution stability. This capability can handle FSI problems with ease including coronary or carotid artery and aneurism applications all the way to models of blood pumps such as LVADs coupled with patient-specific data.
Optimate, a module in STAR-CCM+, also enables intelligent design exploration of the geometrical shape of intravascular devices to improve their implantability, increase their efficiency and reduce their impact on the surrounding blood flow. With Optimate, you can also cost-effectively perform “what if” scenarios and parametric studies to improve on device design and pinpoint areas of high shear stress and recirculation with the goal of minimizing damage to blood cells and reducing the chance of stroke-inducing blood clot formation.
