Best regard,

 

I am working on PEM electrolysis cells, trying to replicate the tutorial from the Ansys Tutorial Guide pdf. But together with my teacher I found certain doubts regarding the definition of the anode_cc3 zone. Since it doesn't look like a complete body. It alludes to the solid of the anode in the bipolar plate, but in the tutorial it appears as an Interior boundary condition and with very different divisions than how fluids and solids are seen in Fluent. If anyone knows how to define that area in that way I would greatly appreciate it, because I have been trying for weeks to replicate everything necessary to simulate electrolysis in my cell model. Thank you for your time and support, I look forward to a possible response.

The image looks like you're displaying the interior zone that's associated with the volume. I'm not familiar with the tutorial, are you trying to set a boundary or cell zone condition?

Hello Mr. Rob, i'm trying to set boundary conditions. However, I already managed to build the interior faces using the Sweep method of meshing. But now the current collectors appear to me as fluids, which is why, by converting them to solid types into fluent, an error is generated since the boundary conditions between the bipolar channels and the collectors. Do you happen to know what else I should do to prevent this error from occurring? 

Thanks again Mr Rob!

If the error is that you have fluid and solid zones next to each other you need to change the bounding surface to a wall. If you set named selections in SpaceClaim with solid-whatever and fluid-something Fluent should do that automatically when you read the mesh in.

Thanks for your advices Mr. Rob, i'll set the Named Selections.
