Inputs Needed to Call the Inlet Slope Trapezoid Function

origin - A 3*1 matrix with x,y,z positions corresponding to the point where the inlet slope will be drawn.

Length - length of the slopes, generally the length of the sedimentation tank

W_Sed - width of the sedimentation tank

l_orifice - length of the opening that will allow inlet flow

h_orifice - height of the opening that will allow inlet flow

b_orifice -

thick - thickness of the slopes

n - number of orifices and sections, one section contains one orifice

bigslope - slope of the inlet in degrees

little slope -

H_Trapezoid -

...

Technical Program Outline

viewtop - sets the workspace so that the user is viewing the top of the object.

viewtop <-- viewtop1

zoomwin - zooms on a window space directly around where the inlet slope is to be drawn.

zoomwin <-- zoom_win(win1, win2)

...

• x: verticalorigin₀ + verticaldim₀/2 + l_orifice/2
• y: verticalorigin₁ + verticaldim₁
• z: verticalorigin₂ + h_orifice + (b_orifice*tan(littleslope))

subtractorifice - subtracts orificebox to create an orifice, using the verticalorigin to select orificebox as the object to be subtracted.
subtractorifice <-- subtractDall(verticalorigin)

...

• x: origin₀
• y: origin₁ - b_orifice - thick
• z: origin₂

array - creates an array to replicate the slab n times, by using the origin to select the slab as the item to put into an array, then specifies that a rectangular array with one row and "n" columns with a displacement of "dist" is to be used to place the slabs one next to the other.

array <-- arrayB(verticalorigin, nrow, ncol, dist)

...

• x: origin₀
• y: origin₁ - b_orifice - thick
• z: origin₂

nrow = l

ncol = n

dist = length/2

union - Unites all the individual components of the inlet slope to act as a single unit

union <-- union_allA

mirror - replicates the original inlet slope drawn by selecting the original inlet slope using the origin, then reflecting it over a mirror line created using mirror_point1 and mirror_point2.

mirror <-- mirror_all(mirror_point1, mirror_point2)

mirror_point1 =

...

win1 =

• x: origin₀ - zc
• y: origin₁ - zc
• z: origin₂ - zc

win2 =

• x: origin₀ + dim₀ - zc
• y: origin₁ + dim₁ - zc
• z: origin₂ + dim₂ - zc
