One rectangle water box, and two electrodes will immerse into the water, if we use solidworks or other plug-ins, how to calculate the resistance between two electrodes? or if apply 10V vlotage on the electrodes,how to calculate the current between electrodes?
nothing in simulation can help you with this. you could check EMSworks but that is mostly for magnetic fields.
i'm a mech so electricity isn't my forte but doesn't electricity follow the path of least resistance? as such isn't your resistance just based on the water between the electrodes?
actually in simulation with the electronics cooling module, you could make the water a solid with the appropriate electrical resistance properties. flow simulation would calculate the current/voltage problem and also output the heat that is generated. but you need to know the properties of the water and it doesn't necessarily answer the question you have. we call this joule heating.
