Hi. Basically I am doing a uni project on electrical safety with water and a big part of it is wanting to test how much water resistance changes with voltage due to the electrochemistry involve. I want to avoid doing a real 240V test where possible (the core part is finding out what happens with resistance at mains voltage) but I have been told on many electrical and chemistry forums that a way to do it is to use software like OpenFOAM which could give me an accurate result. Basically what I want to do is basically have a can full of salt or ionised water with two electrodes attached to it on either side outputting a current of my choice. What is the best way of doing this in OpenFOAM, is it easy to do? I have used Blender to make the mesh (learnt how to do that with openfoam) but how do I make it so a cylindrical object is filled with water and squares on the side of it as electrodes? I am wanting to do this experiment quickly as I have a big deadline and only realised could do this before, is there an easy way as I am new to this software?

I made graduation work with electrochemistry. For this application, boundary elements is much better than finite volumes. But finite volumes will do the task too.

If you use direct current, you have to take into account boundary effects (polarization). Do you need that?

If you want to look more closely into what I have done, you may read my graduation work in ResearchGate. It is in German, but may be you find some help with automated translating:

If you need to know how to calculate this with OF please drop me a line. You may use my boundary condition code instead, especially if you are interested in polarization.
