| real(kind=rk), | intent(in) | :: | h |
Gap between particles (physical units) |
||
| real(kind=rk), | intent(in) | :: | hc |
Critical gap (physical units) If h < hc we use hc to compute the lubrication forces to prevent them from diverging as h -> 0. |
||
| real(kind=rk), | intent(in) | :: | mu |
Dynamic viscosity (physical units) |
||
| real(kind=rk), | intent(in) | :: | R |
Radius of the particles |
||
| real(kind=rk), | intent(in) | :: | un |
Relative velocity in normal direction between the two particles |
||
| real(kind=rk), | intent(in) | :: | norm_rab(3) |
Unit vector pointing in the direction from particle A to particle B |
