I noticed a strong grid orientation dependency while using interFoam with dynamicMeshing. the dynamicMeshing works fine (less initial mesh dependency) when the contact angle is > 40 degree (hydrohil), but deteriate severely when using contact angle close to 5 degree (want to simulation methanol flowing between a thin gap 0.19 mm composed of 2 plates)

following options have been tried so far
1) increasing maxRefinement from 2 to 6 --> no improvement
2) increasing maxCells --> no significant improvement
3) reducing refineInterval from 10 to 5 --> no significant improvement

furthermore, i tried to change
gradSchemes to pointCellsLeastSquares --> minor improvement but the issue persists.

could anybody give me advice what else could be tried to avoid initial mesh dependency in the settings?
