I am currently trying to create a new material for the solid part of my simulation in Ansys Fluent. I'm following a textbook for battery simulation.

I'm following the textbook instructions to add new materials to my battery model, but unfortunately since the textbook uses an older version, there are some differences from the newer version. For example, if I want to add a new material, I want to add UDS Diffusion Coefficients. The unit in the textbook is kg/m-s, but my unit is simens/s. I want to know how to switch to kg/m-s. In unit switching, it can only be switched to ohm^-1 m^-1.

At the same time, UDS Diffusivity and Electrical Conductivity have been merged. Can I change it to define-per-uds in Electrical Conductivity? Will the original default value of Electrical Conductivity of 3.541e+07 not be affected?

Hello,

you should be able to create Units for your desired quantities: 4.4. Customizing Units (ansys.com)
