Fine Mesh Workflow

Process Input Data

Need DEM and Polygons

Format and Check Input data for LaGriT

Create Top surface Mesh (multiple polygons are merged into single surface)

Triangulate polygon to chosen edge_length

Interpolate DEM elevations to triangulated surface

Create 3D Ice Wedge

Offset polygon by rim distance

Triangluate offset polygons

Extrude Outside Ring to Depth

Create 3D Prism Mesh

Create surfaces and stack into prism mesh

Check mesh elevations compare top to DEM data

Add Ice Material to Prism Mesh

Map ice object

Check layer elevations

Check cell materials

Write Final Mesh Files

Identify Boundary Face sets and write ExodusII mesh file

Face sets include top, bottom, sides, and corner faces

End Workflow
