Hello All,

Thanks for the suggestions.

I am doing PhD in engineering and my PhD topic is about to modify a model to simulate Water Quality process in sewer network and i focus on specific output parameter. Actually to build this model with this certain output parameter, there is not so many ways to do this. Both of us have the same basic equation (which developed by other university) and the same output parameter and the funny thing, we are also modifying the existing model based on the same finding in literature review. Of course they way we are building our model is different, he built his model in MATLAB and i built my model in C. But i think this is not sufficient contribution to say that my PhD is giving "Innovative Contribution to the knowledge". He started his PhD not long before me. And i've just come to know recently that his model is much more complete than my one. So, I think what i was doing for 17 months is very useless...

Hello all,

I am so confused and frustated these days since i've just come to know that what i am doing is already done by someone else. I have been doing my PhD for 17 months and i should complete this PhD for 36 months (because my scholarship will be finishing). I was so fool that i didn't notice that someone else also doing the same thing with me. Is someone having any experience or suggestion related with change the PhD topic on these very late time. And how can i tell my supervisor about it (I already can imagine his anger to me).
