No, 90 degrees is generally a good angle - you've reduced the cell count but not created a sharp angle at the axis. It's the right choice in many cases.... The solver is usually very good at the calculation. Can you set the fluid rotation reference (axis) to x (default is z) and recalculate? I'm wondering if that's an issue.Â
