Hallo everybody, I am using a mesh-based-weight window generator. It is clear to me that the coarse mesh must cover the full geometry; my doubt is about the fine mesh. Is it possible to define the fine mesh only in a part of a geometry, for example telling to MCNP to make 5 bins between y1 and...

Thanks for your quick answer. I attach the full input file now. It´s clear to me that I can solve with the SD card, but since the geometry is so easy, my doubt is why MCNP doesn´t calculate the area. I can calulate it, sure. My major doubt is through which surface does it calculate the flux? The...

Hello, after many simplifications my geometry has become very simple: just a box of concrete with a cylinder of steel inside. The source is outside in the air. The cell and the surface cards are like the following: C ******************Block 1: Cells********************** 100 0 99 imp:p=0 99 1...
