Octree Meshing

Octree Meshing

MicroStripes utilizes octree meshing, delivering increased accuracy with significantly reduced run-time. It permits the modelling of structures which are both larger and more detailed than would otherwise be possible. Octree meshing progressively and automatically lumps together computational cells in regions remote from geometric detail. The ultimate size of the lumped cells is limited only by the local permittivity, permeability and highest frequency of interest. Critical but electrically small detail can be captured with an exceedingly high resolution mesh, while the octree meshing reduces the total cell-count by an order of magnitude.


Automated Mesh Generation

MicroStripes ensures that the mesh is suitably fine for the frequency band of interest. The mesh is automatically snapped to geometry and refined on curved surfaces and in dielectric regions. The user can "tweak" the mesh in localized regions, or demand a finer mesh in the vicinity of specified objects. The TLM solver allows rapid change in cell dimensions.


Large Models

Octree meshing and sub-cell models mean that MicroStripes has very low memory requirements. However, for particularly large or demanding models MicroStripes 64-bit EM simulator allows memory usage to exceed 2Gbytes as well as still taking advantage of multi processors. Available for both PC and UNIX 64bit systems.
