For the body, you will have to calculate this yourself based on the y+ you calculated. I would recommend for a start of using a wall function and having your y+ to be anywhere between 30 and 200. We’ll get to actually selecting the wall function later but do recalculate your y+ to as mentioned.
On calculating the values to input into the “Inflate Boundary Layer” (Note it is not the same as Bounding Box Layer addition) lets assume we maintain an expansion ratio of 1.3 (which is default) you will then need to open up Microsoft Excel (for ease of calculating out the layers) and set your calculated first layer (Delta S if you are using the Pointwise Calculator) multiplied by the expansion ratio which remains constant for every increment of the layer. Once you’ve done that you can calculate up to as many layers as you like, but for now lets set it to 5 layers so you should have 5 sets of values with the calculated first layer as the first value. Then you can sum the layers up to obtain the overall layer size.
Once you have all the data above, you can input your “thickness of the final layer” as the final layer size in your data sheet (layer 5) and the sum of the overall layers as the “minimum overall layer thickness”. Just make sure that sum is slightly smaller than the actual sum because of decimal places, you dont want your layers to just disappear. (Example if your sum of layers is 0.51m then input it as 0.5m to be safe). This should settle your boundary layer inflation.
For the inlet and subsequently the ground, this is slightly more grey as to be accurate you have to refer to literature that explicitly states what the minimum inlet cell size near the ground should be. However for a start just leave the values of your “Bounding Box Layer Inflation” to default values and we’ll worry about accuracy later. More important at this point to achieve the inflation layer to allow ground effects to be present first.
So this is a little difficult to characterize as it is based on what you specified as the rotation axis of the wheel and its direction. For this case its either +ve or -ve X. For say -ve X, you will be looking at your wheel from “outside” to the origin and as such for the wheel to move forward, you should expect your rotation to be clockwise. Vice versa for the other defined rotation axis. I would assume that the rotation speed follows the clockwise convention like in this sample case so a positive value of 47.14 rad/s for a Y of -1.
Hope this helps. Do refer to the sample project as it is well made and applies very well to your case.
