1st simulation
i built start mode with 100,000 steplimit.
and equilibriate with, bodyforce=0.0
but not activate stress_bin
However when i showed the result to Prof. he said it’s good
previous sim, i put it in DUMP

2nd simulation
i rebuilt the start mode with only 5000 steplimit
turns out, out2 file has the same
then i activate stress_bin during equilibrate
I name it TASK2…rev in the PC folder
however keep the name TAG the same in winSCP

==============================================
[TASK 4]
START
11 oct
After edited by Prof on the grid number, the START was run well
However i use steplimit 100000

12 oct
I edit the steplimit to 5000 in TASK4_start_rev
and successfuly built initial out2

EQUILIBRATE
Use it to Equilibrate
However stop at step mol 23??

seems that because of the StepGridZero 100,000 is too big given Step Equil is 10,000.

simulation 3, change stepgridzero to 5000–>stopped
simulation 4, stepgridzero 10000, StepEquil 20,000 –>stopped

sim 5, without grid activate, stress_bin=0, StepGridzero 100,000
coz I don’t care…LoL

step_webMoll stop at 91

13oct rerun but still stop at 91
change proc file

BODY_FORCE
i use the out2 from 13oct (with step moll 91)
it works for g04, but i can’t open the grid file

change 8 but stopped

14 OKT
Running use more coarse grid
40
20
20

It worked for the g08, achieve stepwebmoll 100
grid file seems ok

I run equilibrium with coarse grid, just to check whether it will achieve moll 100, however i presume it wont be different coz the stress bin is not activated….and it achieve 100

then i use out2_equilibrate_coarse to run
next body force

TASK 2 – 18 Okt
at tutorial, checking progress with professor.
Able to do averaging and SI conversion
next to find steady state, find the velocity, Reynold number and the flow rate

TASK 2 – 19 OKT
Try to run the shorter timesteps
200,000 timesteps
stepGridZero i set to 20,000

I’ll put my logbook of the Computational USYD here. Just to keep it well documented and traceable. Artemis is a Supercomputer facility in USYD by which I do my simulation of Computational Nanotechnology.
