What does voxel look like in 3D mesh? In particular, are the top and bottom faces of a cell leaning so that their vertices correspond to the vertices depths? <br /> <br />2. To be clear about how to calculate flows, I wonder how are the cells adjacent to the bottom and edge in the sigma model? How is the cut-cell on the boundaries in the sigma-model? In the Z-model it is clear to me that they are represented as a staircase, but in the sigma-model not, since in theory it adapts to the background. <br /> <br />3. How the (land-water) edge of the area to be modeled is defined? is it defined at the vertices or in the center of the corresponding cell? <br /> <br />Thank you in advance, <br /><br />PabloPablo Muñoz2020-06-26T07:50:15Z
