#### Designing a battery cell

Hi all

I want to create a simplified parametric model of a cylindrical cell consisting of a can (C) and a multilayered sandwich (S).

May someone has an idea how to handle this efficient? I could think of calculating the functions and import the parameters, import step or create it in SpaceClaim. More than happy if someone knows another approach or how to do this.
Any chance to link several parametric bodies (so I will manipulate L and R and always get a proper cell) to each other?

Thanks a mil!

You can use SpaceClaim. Please check tutorials on SpaceClaim.

Thanks, @Keyur. Unfortunately, I can´t open the link right now because there is some trouble with my registration... -.-

Update on my approach:

Aim for this model is to use it for a parametric analysis of the cylindric cell adjusting the length and diameter. Therefore I want to brake it down in the following steps.
1) Simplify the cylindric cell as a hollow cylinder with spriales in in the inside
2) Create the hollow cylinder
3) Create one spiral (the radius must be aligned with the radius of the cylinder) as a layer of the jelly roll
4) Assemble spirals and cylinder as a 3D modell

1) And 2) are done. When designing the spiral I get an error in SpaceClaim. May someone can help me with this one?

Comsol has a tutorial but it didn´t help me with ANSYS: https://www.comsol.com/blogs/how-to-build-a-parameterized-archimedean-spiral-geometry/

PS
A cross section of an actual cell looks like this - if someone has a better approach I would be more than happy to hear it: https://www.mpoweruk.com/images/lg_cylindrical.gif

Unfortunately I could find the missing bit I need for my issue.

Is there any explicit help with parametric spiral shapes in Space Claim and the assembly in a manner that it enables scaling via the parameters?

Hi Keyur

This just the manual as website. How can use the preset curves? Especially the "Archimedes Spiral"?

If you have parameters of the equation with you, the equation is constructed in the Options panel.  You can enter an equation in the input fields.

If you want to create custom equation then please see custom equation in the help link provided.
