DLD Array Generator

A package to generate DLD arrays in DXF format. All distances in micrometers, angles in degrees.

The array is parameterized by attributes of the DLD_Array class. Initializing an instance sets up an array with default values. Each of the attrbutes (outlined below) can then be set as desired. When the configurtation is complete, call generate(filename) to output the array as in a .dxf file format.

Installation

pip install dld-array-generator

Examples Usage

from dld_array_generator import DLD_Array

filename = "DLD example"

g = DLD_Array()

# Update channel desired channel parameters
g.C_D = 10e3 # channel length
g.C_L = 200 # channel width
g.C_N = 2 # bend pairs (producing 4 bends in total)

g.generate(filename)

Attributes

Channel attributes:

C_D = total channel length
C_L = channel width
C_N = number of channel bend pairs
C_separation = distance between parralell channel segments

Turn attributes:

T_N = number of walls in turns
T_W = thckness of walls in turns

DLD-array unit cell attributes:

D_D = center-to-center downstram pilar distance
D_L = center-to-center lateral pilar distance
D = pilar dimater
theta = array angle

IO port attributes:

IO_D = diameter of inlets/outlets
IO_F = filet radius for inlets/oulets
IO_L = IO stem length

O_LP = percentage width of left outlet
O_S = separation of outlets
O_BR = bend radius
O_D = downstream distance for outlet before bend
