I have few questions. If you can guide 1. Why you have selected slice material for battery? 2. When drawing cylinder, why didn't you used mirror command to make all duplicate cylinder? Does it affect result? Or is there any other way?
@@FrontiersInCFD Please explain this When drawing cylinder, why didn't you used mirror command to make all duplicate cylinder? Does it affect result? Or is there any other way? like solid work and pro-E have option Reply
I have drawn model as you told me . But i am not getting contour animation same pattern as you shown here. Can you tell me email so that i can show you image and you can point out my mistake
Sir, I followed the video exactly, but during the "Run calculation" step, I encountered a "floating point exception" warning. What could be the reason for this?
@@FrontiersInCFD Sir also one more doubt , in previous 16 cell simulation you put boundary conditions of wall in "wall-cell_1" but in this video you are putting boundary conditions in "cell wall contact region" !! why so ??
I did the analysis the initial cell temperature was 330 k , the inlet was 300, the final temprature in the contour plot is showing 315.24, I'm able to see the temperature reduction but when i am finding values at outlet (exit) the temperature which i am getting is 307, and as I'm increasing the velocity the temperature decrease i.e 303,302 . Whereas initially if the velocity is increased it shoulf carry more heat right , could you please guide me what am i doing wrong

I'm telling you the problem. The problem is with your meshing, not the setup. This problem appears while you calculation encounters a division with 0. Checkout your mesh quality and you'll find its standard deviation is 0. Now how to solve this problem? --> make a mesh of your model from beginning and avoid 0 standard deviation in quality checking. You'll get the solution in sha Allah

there is interaction between two materials, which results in heat transfer other option is to go for conformal meshing and merge topology.

Yes it affects the result as you will see no heat interaction between two bodies i.e pack and cylinder

what was time step size, if you have different mesh size then change mesh size
Sir. The cells are like floating in the fluid zone. Can you please explain the position of the cells
Along the base of box
Sir . How to take results for this CFD. Like Graph and Table values for the Pressure and Temperature.
In Result section select respective contours and generate.
Sir Can you give me a journal based on this analysis...
You mean research paper
Yes sir send the link of research paper please....@@FrontiersInCFD
Sir after running simulation , the contour is showing only blue colour , no variation is shown !! Please Help !!
Look like error in boundary conditions applied
@@FrontiersInCFD Sir also one more doubt , in previous 16 cell simulation you put boundary conditions of wall in "wall-cell_1" but in this video you are putting boundary conditions in "cell wall contact region" !! why so ??
depends on what name is specified in mesh section
hi bro can you please guide me how to design a lithium ion cell from scratch ?

If velocity is less fluid will get sufficient time to exchange heat
Sir, in results section it shows completely black

@@FrontiersInCFD it means I have to change mesh size bigger?
The calculation proceeds to about 5 percent, then a warning message appears.“floating point exception”
