UDS Diffusivity is not showing in the material box. I saw the help section in fluent and got redirected to

"https://ansyshelp.ansys.com/account/secured?returnurl=/Views/Secured/corp/v241/en/flu_ug/flu_ug_materials_task_page.html%23flu_ug_Create_Edit_Materials"

where I found written that shown in image 1 attached. Then I went back to my fluent student version 24, which shows image 2 attached. There us no option for uds diffusivity either in solid or liquid. I am using MSMD batter addon. How and where can I get this option? Please help me in moving forward. I am stuck here. I am happy to share other details if required.

Here when you activated the dual potential MSMD model (which shows only MSMD model in ansys 24), while getting activated, it was poped up in console that "new property UDS diffusivity has been added", this is absent in my case. Why is it so? I am also not able to add this using "user defied scalar" under the "User-defined" tab at the top (attached image 3). Please help in this. Thanks in advance

Hi, you can find UDS Diffusivity under Fluid Material Properties. Set it to 'defined-per-uds' and click on Edit. You will get the pop-up to enter UDS Diffusion Coefficients.
