Hello everyone,

I am trying to model an electrochemical reactor (cylinder with shell for geometry) with a potential difference of 36 V, and to do so I am adding "Voltage" under "Steady-State Thermal-Electric Conduction" on Ansys Mechanical. I inserted a low potential (0 V) and high potential (36 V) across the innermost cylinder, but both still have a question mark next to them.

I tried setting the boundary condition across the two faces of the cylinder or even the two circular edges, but nothing has changed. Does anybody know how to fix it?

Thank you kindly!

Hi

You are missing resistivity (electric).

Make sure Isotropic Resistivity is defined for your material in Engineering data.

All the best

That fixed it, thank you very much!

Thanks for confirming - That is great to hear.

Closing the post as others might encounter the same issue.

Anything else please open up a new discussion.

All the best
