| 7 | 3. A 3 AU separation simulation now will take about 5 days on 120 cores. I tested the resolution on single AGB star and it has a difference. The size of the simulation zone is $48au^3$. The previous resolution is $120^3$ base grid with 2 level of AMR. The current AMR is 3 while the base grid resolution is the same. The finest physical resolution is 0.05au thus the AGB star has 18 cells across its radii. The photosphere has 21 cells. |

| 9 | 4. I calculate the strength of tidal force by: |
| 10 | |
| 11 | $(\frac{M_{com}}{(d-r_{AGB})^2}-\frac{M_{com}}{(d+r_{AGB})^2})/\frac{M_{AGB}}{d^2}$ |
| 12 | |
| 13 | where $d$ is the binary separation. Substitute $d=3au$, $r=1.5au$, $M_{AGB}=M_{\odot}$ and $M_{com}=0.5M_{\odot}$ you will get the value is close to 0.5 which is 50%. |
