$FOAM_TUTORIALS/finiteArea/surfactantFoam/planeTransport.The separation of geometry and fields also applies to finiteArea conversions, e. This allows loading of individual or multiple regions, and permits fields such as T (temperature) that span multiple regions as well as fields such as U (velocity) that only apply to specific regions. The EnSight file format is well suited to multi-region content, enabling each OpenFOAM region to correspond to a separate EnSight case file, e.g. As part of the improvements, a new -finite-area option has been added (similar to foamToVTK) for support of finiteArea output. This greatly simplifies post-processing and conversion for conjugate heat transfer (CHT) cases. The foamToEnsight utility now supports multi-region selection and a new -allRegions option. $FOAM_SRC/sampling/surface/distanceSurface.$FOAM_SRC/sampling/sampledSurface/distanceSurface. ![]() $FOAM_TUTORIALS/incompressible/simpleFoam/squareBend.$FOAM_TUTORIALS/compressible/rhoSimpleFoam/gasMixing/injectorPipe.$FOAM_TUTORIALS/compressible/rhoSimpleFoam/squareBend.The definitions of the filtering algorithms (v2106 and v2012 filters) were performed in partnership with Sven-Eric Salecker (NAVASTO GmbH, on behalf of AUDI AG) for non-trivial test geometries. If the area-weighted distance of a topological region is greater than the given threshold, the entire region is rejected: This filter acts by checking the distance of the resulting faces against the original search surface and filters based on the area-weighted distance of each topologically connected region. To address this, the new proximityRegions topology filter combines face proximity information with topology segmentation. In earlier versions the filters would either fail spectacularly by choosing the incorrect region, or become tedious to specify. This could arise from a so-called double-dee pipe, or a sleeve with an actuator shaft: for the following scenario where the thin-walled pipe separates different zones topologically: The new proximityRegions topology filter addresses a similar problem, e.g. In this mode it works much like a cell cutting method for generating surfaces. In addition to the original purpose of distanceSurface (to create a sampled surface at a distance from an input surface), it can also be used to sample at a zero distance from an input surface. ![]() This version provides an additional filter method for distance surface, continuing the changes from OpenFOAM-v2012.
