Borehole test V1b /scratch/sft/tam/SALT/borehole/3D_stack_v1b April 11 2018 Modified to shift zones forward closer to actual build location The mesh remains the same, only the heater zone nodes are changed. Shift Heater from 3.5052 to 2.3876 meters. All else remains the same. MATERIAL ZONES: tet_full_material.zone (no change) borehole with radius 2 inches 2 observation nodes top 6 inches from borehole wall 2 observation nodes bottom 12 inches from borehole wall Background 1 has 223234 nodes. #nodes/nnodes is 0.937536478043 Borehole 2 has 14317 nodes. #nodes/nnodes is 0.601284280419E-01 Obs top_left 3 has 139 nodes. #nodes/nnodes is 0.583771150559E-03 Obs top_right 4 has 139 nodes. #nodes/nnodes is 0.583771150559E-03 Obs bot_right 5 has 139 nodes. #nodes/nnodes is 0.583771150559E-03 Obs bot_left 6 has 139 nodes. #nodes/nnodes is 0.583771150559E-03 HEATER ZONES: These zones overwrite the tet_full_material.zone zones above. Update to Shift Heater forward from 3.5052 to 2.3876 meters. V1 (old) y= 3.5052 to 3.7084 V1b (new) y= 2.3876 to 2.5908 There are 3 different radius lengths you can choose from 2, 2.5, and 3 inch. -rw-r--r-- 1 tamiller sft 9560 Mar 16 11:40 heater_2_radius_b.zone -rw-r--r-- 1 tamiller sft 7635 Mar 16 11:40 heater_2half_radius_b.zone -rw-r--r-- 1 tamiller sft 5710 Mar 16 11:40 heater_3_radius_b.zone Heater Zone Length 8 inch (.2032m) y=3.5m to 3.7032 grid y 3.505 to 3.7084 and within radius distance for each zone.

Now that we've built it, the front of the heater is actually located at about 2.3876 m from the front of the hole (i.e. y = ~2.39) in inches, it's located 36 + 26 + 26 + 6 inches back from the front of the hole, or 94 inches. Attached are Phil's notes including sketch on page 2, showing the lengths. Charge code is DS1400 00000. Phil said to let him know if it'll take >1 day. If there's anything else you need, just let me know.
