Grid Project:  SALT Stoller Canister

Version History

Purpose of Project

Build a 3D mesh representing a heat canister for FEHM simulations. This is a prototype cannister with legs, cement floor, and air. Quarter cylinder design based on dimensions and description in 'Independent Design Analysis and Verification of "Hearter Canister" as Part of the Salt Defense Disposal Investication', Appendix A.

The mesh is 3D tetrahedral built by stacking 2D X,Z geometry in the Y direction.

The mesh is 3D tetrahedral built by stacking 2D X,Z geometry in the Y direction.
Coordinate 0,0,0 is located at cannister bottom lower left.
Fine resolution on inside of can and near the sides at .02 meters. The can wall has .01 meter thick buffer inside and outside. Resolution furthest away from can is .2 meter spacing.

Meshing Method:

Create surface that will be stacked.
  lagrit < tri_surf.lgi
  cp outx3dgen tri_surf.out.txt
  cp logx3dgen tri_surf.log.txt

Make surface into nice triangulation.
  lagrit < smooth_recon.lgi
  cp outx3dgen smooth_recon.out.txt
  cp logx3dgen smooth_recon.log.txt

Write run the LaGriT command file for stacking surfaces.
write_stack_lgi.py > stack.lgi

  lagrit < stack.lgi
  cp outx3dgen stack.out.txt
  cp logx3dgen stack.log.txt

Connect into a Delaunay tet mesh.
  lagrit < stack_connect.lgi
  cp outx3dgen stack_connect.out.txt
  cp logx3dgen stack_connect.log.txt


Color materials and and write fehm files
  lagrit < fehm.lgi
  cp outx3dgen fehm.out.txt
  cp logx3dgen fehm.log.txt

post processing
  lagrit < write_zero_col.lgi
  cp outx3dgen zero_col_list.out.txt

get inner shell and heaters
  lagrit < get_inner_shell.lgi
  cp outx3dgen can_shell_list.out.txt
    cp tmp.zone can_sleeve.zone
    cp tmp2.zone can_sleeve_htop.zone
    cp tmp3.zone can_sleeve_hside.zone
