Control the size of the output mesh after Automatic Remeshing occurs

Hello all!
I am having troubles with a "Laminar Two-Phase Flow, Moving Mesh" model: the mesh elements are becoming very distorted and eventually the simulation crashes. Therefore, I have added the "Automatic Remeshing" option (I have tried changing the "Condition Type" and the options in each condition type).
However, I have found that each time it remeshes it creates a finer mesh and, thus, it is easier that a mesh element does not satisfy the automatic remeshing condition. Furthermore, if the mesh is finer the simulation takes longer to run. In the end, my model enters a loop where it remeshes basically every step the solver takes (for example, my last simulation remshed 26 times in 0.2 seconds) and it eventually crashes because "can't find a solution that satisfies the tolerance" (I have reduced the tolerance to less restrictive values).
Does anyone know how to control the size or the properties of the output mesh? Or does anyone have any recommendations for this problem?
Thank you very much in advance.
PS: I've attached a screenshot of the original mesh and the final mesh (before it crashes)
