I am fairly new to Delft3D and I have this general question. I use Delft3D and sometimes DelftDashboard for the set-up of a flow calculation. Since I have my own bathymetry I don't use DelftDashboard for that, but I still would like to incorporate some convenient features of it. <br /><br />1. Is it possible, i.e. in QUICKIN or RGFGRID to formulate a rectangular grid that follows the coastline (or a maximum z-value near the coastline) in a similar easy way, like you can do in DelftDashboard?<br />I mean that you create a grid that stops where the bathymetry is 0m?<br />Is that possible, and if so, how is that possible?<br /><br />2. Follow up question. Is it possible to cut the grid off where the sample (my own bathymetry, xyz file) ends on the open boundary (sea) side of the sample?<br />For example in QUICKIN or RGFGRID?<br />How I know is the best way to define a polygon that 'tries' to follow the sample best, but this is not exact. <br />I want that the grid has exactly the same edge, boundary as the sample. Is that possible?<br /><br />Thanks.<br /><br />Regards,<br />RobertRobert de Boer2013-11-06T18:48:55Z
