- In the 2 Dimensional case

|
we use a potential of the form:
|
|
|
$`\Phi _p^{\epsilon} = -{m_pG\over {\sqrt {d^2+\epsilon^2}}}`$
|
|

$`\Phi _p^{\epsilon} = -{m_pG\over {\sqrt {d^2+(\epsilon R_H)^2}}}`$
|
|
|
In 2 dimensional models we do not only have the problem of avoiding the singularity but we choose a potential that allows to mimic the average influence that the planet would have on the vertical gas column.
|
|
|
A value often used for the smoothing is $`\epsilon = 0.7H`$ where $`H`$ is the disc scale height.
