Hi and Peace be unto All !!

Im an MSc student, who recently started learning Slb Eclipse. Im trying to construct a Natural Fractured Reservoir for my dissertation. In the process, im coming across different hurdles in the Grid Section. I tried to search for a fractured reservoir construction model sample, but couldnt find any.
Ive tried to construct a sample model wid Corner Point, Dual Porosity, Dual Permeability, Transmisibility functions

I have many doubts, like
1. If i should be using Corner point or Block centre to build my model?
2. Wt ol keywords should i probably be using for my Grid? IN my Dual porosity keyword, ive used LX,LY,LZ, SIGMAV..should i be using anymore ?? as i keep getting errors..

Thanks a lot for ur reply !!
Peace be upon you !!
