32-bit is no longer supported for new versions of the software but you can get the most recent 32-bit version here --> http://www.nic.funet.fi/index/elmer/bin/windows/2014/
Maybe you can refer to this paper ' Diffusivities, viscosities, and conductivities of solvent-free ionically grafted nanoparticles', I hope it can help you.
The elmer software seems to be good in terms of what i saw in the youtube videos , but none of the tutorials (including the pdfs or videos) show how to build objects , how to setup the environment etc. Please kindly help Ron Reiserer
