Finally I found the way to import the model. I made some render of the model with materials. I am running out of time, the contest will end in one day time, I am working in the nParticles, hopefully I will get the particles, fluid and materials as well as the final render before the end of the contest. It is possible to extend the contest? What is the resolution you are looking for the final render? It will take long time depending of the resolution, material and the nParticles.
I will appreciate any feedback. Please, don't hesitate to contact with me if I could be in further help.
