How to Use Experimental Data in Fluent?

Floyd · June 8, 2010, 05:56

Hi

I am a student and currently doing a research on a thermal management system of a cylindrical lithium ion battery. The discharge temperautre of the battery was measured experimentally and that was actually a temperature V.S time curve. I would like to know how I could put the whole set of temperature V.S time data into fluent to carry out my simulation?

Thanks!
Floyd

I would like to know if it possible to use a time dependent heat source term in the simulation since I only see the constant source term setting. thank you!

Hi,
I would like to know , how to plot the C-rate graphs and voltage distribution using MSMD battery module in ANSYS fluent

C-rate graphs and voltage distribution are using to estimate parameters for electro-chemical models

Best regards

Thanks for the reply

How we can plot the current distribution graphs which should show variation in cell bodies.

Graphics -> contours -> User defined memory (under contours of) -> Magnitude of current density

Best regards

Thanks! It works

i am simulating Li-ion battery after I pop-up the Run solution message reflects" zone 16 is not connected to conductive zone ". How to resolve this .Is their any option to resolve this error without changing the geometry.

AlexanderZ · March 11, 2018, 22:36

as far as I know, usually the only way is to change geometry
without geometry I can't advice

best regards

I have attached a picture and i stuck with an error while simulating in ansys fluent. the file is attached below. How to solve the overlapping with interface zones

obviously you have problems with mesh.
Generate new one, first of all delete all contacts

best regards

Thanks I will try and let you know.
While simulation error shows : " Divergence detected AMG solver :temperature".
How to get rid off from this error.

I believe, that for your case this error comes from problem with mesh.

best regards
