BubbleAlgorithm
Bubble Algorithm in order to capture internal pressure of air/gas entrapments
The BubbleAlgorithm is switched on if BUBBLE_DoTheManagement is different from zero.
BUBBLE_DoTheManagement = 1 (original implementation) : BubbleSemiimplicitPressure is applied
BUBBLE_DoTheManagement = 2 : BubbleImplicitPressure is applied
The Bubble Algorithm clusters the free surfaces by connectivities, computes the volumes of the individual clusters (possibly entrapped also with the geometry) and computes the pressures corresponding to the tracked volume changes.
The relevant MESHFREE quantities are
| Quantity | Index |
|---|---|
| BubbleDetection | %ind_bndBubble% |
| BubbleVolume | %ind_volBubble% |
| BubblePressure | %ind_pBubble% |
| Time steps an invalid Bubble was kept | %ind_nTS_InvalidBubbleKept% |
| List of members: | |
|---|---|
| BubblePressure | approximate pressure of closed bubbles |
| BubbleDetection | detect topologically connected clusters of free surface |
| BubbleVolume | approximate volume of topologically connected AND closed clusters of free surface |
