Hello Chung,

Unfortunately it seems you did not upload all your files properly and I guess neither me nor other users can read your post properly. Could you please rewrite it?
Concerning extension *.grd it is reserved for regular grid. If you work with irregular grid (DFlowFM) you have NetCDF *_net.nc file format (in the upcoming version also UGRID).

If I remember correctly the plots you unsuccessfully tried to attach, you should explore more options in combination with polygons. As example try:
1. Create Rectangular or Circular Grid (meny Operations) ---> OK
2. Edit --> Polygons --> New
3. Draw a small polygon in the middle of your network (or any other place so that polygon overlaps with network)
4. Now lets refine in the polygon (since polygon from point 3 is by default active) by: Operations --> Irregular Grid Coarseness --> Refine Casulli
5. You have now locally refined network

You can repeat analogically steps above to Derefine some places. Also if you draw a polygon you can then delete a piece of network that is within that polygon.

Kind regards,
Michal
