I'm an engineer who needs to do FEA for the first time. I need to model chemical diffusion in a liquid in a container with specific geometry. For now fluid is assumed to be not flowing.
What features do I need to look for in FE software to get this done? Diffusion doesn't fall under fluid dynamics does it? It's not thermal (though I think it may be mathematically similar) or structural either.
Specific software suggestions are also welcome. I suspect my needs are basic so ease of use would be nice too.
