Immersed boundary method (IBM) based direct numerical simulation of open-cell solid foams: Hydrodynamics

Numerical Analysis of the Immersed Boundary Method for Cell-Based Simulation

Mathematical modelling provides a useful framework within which to investigate the organization of biological tissues. With advances in experimental biology leading to increasingly detailed descriptions of cellular behavior, models that consider cells as individual objects are becoming a common tool to study how processes at the single-cell level affect collective dynamics and determine tissue ...

Parallel Spatial Direct Numerical Simulation of Boundary-Layer Flow Transition on IBM SP1

The spatially evolving disturbances that are associated with laminar-to-turbulent transition in threedimensional boundary-layer ows are computed with the PSDNS code on an IBM SP1 parallel supercomputer. By remapping the distributed data structure during the course of the calculation, optimized serial library routines can be utilized that substantially increase the computational performance. Alt...

On the numerical oscillation of the direct-forcing immersed-boundary method for moving boundaries

In recent years, the immersed-boundary method that is based on the structured mesh has gained considerable popularity in computational fluid dynamics for solving complex and moving-boundary problems. Despite its wide applications, so far there is not a unified definition of the method, possibly because there are many variations in the existing implementations. Here we follow the classification ...
