Shown is a computer simulation of platelet aggregation in a 50-micron vessel with flow velocity of 100 microns/s. Red blood cells are treated as continuum. Platelets are allowed to adhere anywhere on the vessels walls and to each other. Three activated platelets are placed on the wall to initiate the process. The activated platelets are shown in red, the triggered platelets are shown in green, and the passive platelets are shown in blue. This research was funded by the National Science Foundation, as part of the Interagency Modeling and Analysis Group's (IMAG) Multiscale Modeling Initiative. This initiative is administered by the National Institute of Biomedical Imaging and Bioengineering (NIBIB), a part of the National Institutes of Health.
