Hi,

I have been using Ansys fluent for quite sometime and now its my first time trying to simulate the planar geometry SOEC using the SOFC Unresolved Electrolyte module. Its been a month that I have been facing issues in setting up the boundary conditions correctly. I have gone through the manual and its been of a great help but still the problem persists.

The problem is that there is no electrochemical reaction happening inside and the species remain as it is, as it is defined at the inlet.

To be specific I am having issues while selecting the accurate voltage and current tap surfaces, i have got an option of series of walls and interfaces, i have done multiple hit and trial method with data from different sources available on the internet but its of no use

Secondly i want to know if i have to individually set the electrical boundary condition for different interfaces in the BC task page or is it enough to specify the system voltage in the SOFC Model parameters tab.

Lastly, in the cell zone conditions i need to specify the porosity for cathode and anode but the porosity tab is only available if i opt the them to be fluid and not solid.
