A new isosurface extraction method on arbitrary grids

Revisit to the THINC/QQ scheme: Recent progress to improve accuracy and robustness

“…As mentioned before, the thickness of the jump transition spans over two or three grid cells, which makes the thin film of stretched interface not visible due to the inadequate grid resolution. It is noted that we use a toolkit called isoap 64,65 in this case for post‐processing to retrieve the interface from the VOF field. It is seen that the thin interface of the most deformed structure is well resolved by the present scheme with high resolution that is comparable to isoAdvector‐plicRDF which retrieve the interface via an explicit geometric reconstruction.…”

gVOF: An open-source package for unsplit geometric volume of fluid methods on arbitrary grids

“…the isosurface corresponding to the isovalue 0.5 is constructed using the procedure proposed by López et al [54] (see the example of Fig. 1).…”

gVOF: An open-source package for unsplit geometric volume of fluid methods on arbitrary grids

“…( 1) are presented (a brief description of each one is summarized in Table 1). It must be mentioned that gVOF requires the VOFTools v5 [45,52] and isoap [54,57] external libraries. For the sake of brevity, the calling convection and the list of input and output parameters for each routine described hereafter, as well as others auxiliary routines not mentioned here, are left to be provided in the user manual included in the supplied software package.…”

“…The details and assessment of the voxelization procedure implemented in this routine will be published elsewhere. It must be mentioned that the isovtkgrid routine, which is part of the isoap library [54,57], is also used in this work to write isosurfaces extracted on arbitrary grids.…”

“…Two test programs are included in the supplied software package to assess the performance of the implemented algorithms to solve different static (Section 4.1) and dynamic (Section 4.2) problems with prescribed velocity fields using arbitrary grids. The following grids with convex and non-convex cells are considered (further details of the generation of grids used in this work can be found in [54] and some of these non-uniform grids are also included in the supplied software package):…”
