Collapsing Prism Layers
 

Hi there, I'm having trouble with some collapsing prism layers (See image attached. I have three separate surface controls for the wing (left), hinge (central) and fan (right), each with custom prism layer first cell heights according to their local Re number and custom number of layers.

Should I adjust these controls to all have the same prism layer settings to avoid this collapsing issue? Its quite a key area of interest to my results. Any help appreciated.

At the minimum, play with the prism layer settings under models. Set the prism layer minimum thickness to .01% if you haven't already so it basically never retracts. Maybe set the layer reduction to 10% so it removes layers like it is but keeps at least 10%.

*Sorry, under the meshers drop down, not models
