<Step 1>

Make a Box(Pack) & 24 Cylinders(Cells)

HOW

1.make 'Fluid Flow(Fluent)' tool box

2.click 'Geometry-DesignModeler'

3.set the coordinates system and create 'Box' and 'Cylinders' by using 'Create-Primitives' and typing specificated numbers on the 'Details View'

We need total 48 cylinder parts ( 24 for cells with radius 9 and 24 for cell casings with radius 9.5)


<Step 2>

Make Inlet & Outlet

HOW

1.Make 'Cylinder' on the left side with specificated numbers

2.Click 'Create-Pattern' function. Then set the direction, geometry(cylinder) and the numbers of the Offset&Copies.

3.Using 'Pattern' function one more with all the patterned cylinders 

Inlet

4.Make 'Outlet' with 'Create-Primitives-Cylinder' as well (No picture)


<Step 3>

Geometry Settings

 

1. 'Form a New Part' with all the Inlet Cylinders

2.Unite Inlet, Box and Outlet with 'Create-Boolean'

3. 'Form a New Part' with all the battery cells and cell casings(each)


<Step 4>

Mesh Settings

 

1. Generate Mesh with the size of 2mm (0.002m) 

※ check your computer configuration and put the proper number

default Sizing -> 0.002m Sizing

2.Set 'Named Selection'

Click all the inlet cylinder's face and outlet cylinders's face with 'Create Named Selection' function

Inlet / Outlet

Using 'Hide all Other Bodies' and set 'Named Selection' as well

※ Do not miss faces inside

Check the ground

If you have yellow sign then click 'Update'


The part 2(Setup&Result) will be coming soon...
