How to import Grid(D-Flow FM) into Delft 3D-Flow
Youngling Post: 1 Join Date: 3/30/15 Recent PostsDelft3D-Flow –flow input-domain-open grid command, only .grd file (grid(RGFGRID)) could be imported. Then how to import the flexible mesh into Delft3D-Flow?

When saving a grid (i.e. exporting) you can only save a structured grid in "Grid(RGFGRID)" and an unstructured grid in "Grid(D-Flow FM)" format. An unstructured grid cannot be saved in the structured format "Grid(RGFGRID)".

The option "Convert Grid -> Irregular to regular" doesn't make effect. Do I have to do something before with my grid?

When converting a grid from irregular to regular (or vice versa) only the colour of the grid changes. It changes from dark blue (structured grid) to light blue (unstructured grid). Also at the corner point the nodes become visible in case of an unstructurerd grid. The grid itself doesn't change, which might suggest that nothing has happened, which is not true. The status has changed to another 'mode' and other commands have become active; see the commands in grey (inactive) and black (active).
With kind regards,

Youngling Post: 1 Join Date: 10/23/18 Recent PostsHello. I have this problem too. I switch irregular grid into regular grid but lots of area of my unstructured grid removed. How can I use this full unstructured grid in Delft3D-Flow when input file has no _net.nc ?
Thanks for answering to my question.
