  Hello,
  I'm using Ansys 2021 R1 Academic Version.
  doing battery thermal management analysis for my final year project in ansys fluent using battery module- MSMD.
  I can't find UDS diffusivity in Create/Edit Materials under properties.

  for solids, thermal diffusivity = k / (rho * Cp)nnAre you using UDS?n

  Yes using UDS.nI'm new to ansys so I'm following this tutorial
  I've followed every step shown in this video but still I can't find UDS diffusivity under properties. n

  The UDS diffusivity is mass diffusivity. I believe you need to set the material as fluid to find UDS diffusivity. n
