Mesh Generation

• Rapidly generate high-quality unstructured Voronoi and triangular grids

• Choice of state-of-the-art mesh generation algorithms

  • High-quality multi-level optimization

  • Fast Delaunay refinement

• Default parameter settings and quality presets allow generation of good meshes without much need for parameter adjustment

• Optional advanced parameter settings allow fine-tuning of generated meshes to optimize cell quality and minimize the number of cells

Flexible Geometry Input

• Import points, polylines and polygons from GIS or CAD data, or digitize manually in the AlgoMesh user interface

• Use AlgoMesh’s automated geometry clean-up algorithm (new to version 2) to save time pre-processing and quickly simplify areas of tight geometry before meshing for a clean, efficient mesh without over-refinement

• Easily create holes or cut out unnecessary areas of a model

• Resample polylines for precise control over input point spacing and resulting mesh cell sizes

  • Fixed or geometric intervals between points

  • Easily adjust sampling intervals and regenerate the mesh from the same input geometry, without the need to import again each time

• Fit cubic spline curves to input polylines to represent curvilinear model features

  • Splines have adjustable tension to control curve shape, from smoothly curving (low tension) to almost linear (high tension)

Powerful Modeling Tools

• Create any number of property value fields to be sampled over a model

  • Anything from a set of sample points with associated values (e.g. a regular grid) to a complex polygonal domain may be used

  • Interpolate property values at any point in the mesh

  • Export interpolated property values at mesh cell centers or vertices to CSV or common GIS formats

• Select cells at boundaries, along streamlines, at points or within polygons, to aid in constructing model boundary conditions

MODFLOW 6 and MODFLOW-USG Support

• Export generated meshes to MODFLOW 6 (new to version 2) or MODFLOW-USG model files

  • Single or multiple layers

  • Steady-state or transient

• Voronoi cells guarantee perpendicular flow directions between cells for accurate finite-volume simulation

• Map TIN-interpolated, CSV table, raster or polygon property fields to model cell properties (DISU / LPF / BAS / NPF / STO / IC)

  • Layer bottom and top elevations

  • Hydraulic conductivity (Kx, Kz)

  • Specific storage

  • Specific yield

  • Initial head

• Use property fields to generate model boundary condition files

  • Pumping wells (WEL)

  • Drains (DRN)

  • Constant head boundaries (CHD)

  • General head boundaries (GHB)

  • Recharge (RCH)

  • Evapotranspiration (EVT)

  • Rivers (RIV)

  • Time-Variant Materials (TVM)

• Import CSV files to directly map boundary conditions and property data on a per-cell basis

• Export interpolated property values at cell centers to assist in manual creation of input files for other packages

• Use Lateral Connection Groups to precisely control the generation of lateral flow connections in the discretization file

  • Create vertically-nested grids (vertical sub-discretization)

  • Generate cross-strata connections to simulate flow across vertical faults

  • Construct vertical flow barriers that block lateral flow entirely

• Import binary head and drawdown results from MODFLOW-USG as property fields

  • Export to CSV for visualization in other software (e.g. Surfer®)

  • Reuse steady-state heads as initial heads in a transient simulation

  • Automatically interpolate heads onto a new or modified mesh

HydroGeoSphere™ SUPPORT

• Create high-quality 2D triangular meshes and export in .AH2 format for use in fully-integrated HydroGeoSphere™ (HGS) models

• HGS grok script command "read algomesh 2d grid" allows building a 3D HGS model from an .AH2 file

• Select node and element sets within polygons, along polyline paths, or manually, and export nchos and echos format selection sets to build boundary conditions

Interoperation with Other Tools

• Use AlgoMesh as a powerful alternative mesh generator for FEFLOW®

  • Optionally import FEFLOW® ASCII supermesh (.smh) files

  • Export triangular mesh shapefiles for import into FEFLOW®

• Export to 3D TOUGH2 MESH, 2D or 3D FEM (.fem) or 2D flexible mesh (.mesh) files

• Import points, polylines and polygons from many common GIS and CAD formats

  • SHP, DXF, DGN, MID/MIF, GML, BNA, GEOJSN, XYZ and more

• Export cell geometry, vertices and vertex property values to many common GIS formats

  • SHP, MID/MIF, GML, BNA, GEOJSON and more

• Create VTK format files for 3D visualization of cell geometry and flow connections with ParaView®
