ASCOMP has developed a new fully automatized version for microfluidics applications in bio-devices, using the IST (Immersed surfaces Technique) technique to map complex components/geometries into a simple rectangular Cartesian grid. Near wall regions are treated by another new feature, namely the BMR (Block-based Mesh Refinement), in which sub-scale refined blocks are placed around each structure or obstructions, up to 4 levels of refinement. The connectivity between blocks can be achieved in parallel (using MPI) up to 8-to-1 cell mapping. The combination IST/BMR can save up to 70% grid cells in 3D.
