Create netCDF from a text based triangular mesh with(out) Quickplot - Forum - Delft3D Flexible Mesh

Hi Dmitry, A lot is possible, but I'm not sure I understand exactly what you intend to visualize; I don't see how your figures show drying and flooding -- I think that I'm looking at a figure of the water depth. FM can also write out the water depth to the map-file and you can visualize it and optionally clip (make transparent) the cells for which the water depth is below a certain threshold. If you want to color the dry cells light blue then you have to add that as a first layer to the plot. You can either plot the grid (not hiding what is on the background map within the cells that are sometimes dry) or you can select the quantity "Topology data of 2D mesh - face indices" and select "Colour uniformly" and select light blue. Create the plot. Add to this plot the water depth plot with areas with water depth below for instance 0.01 m clipped (transparent). That should give you a figure that looks similar to your figure if I interpret it correctly. If your model is bigger and actually included the whole sea area on the right, and you intend to visualize only the area that is initially dry, then that's also possible. In that case you'll have to select the 1st time step of the water depth and define a variable, e.g. "initial water depth", via the button on the bottom row of the QUICKPLOT dialog. Subsequently, you select All time steps, and define another variable, e.g. "all water depths". Then you select from the list of opened files, the option "<user defined variables>" and open the "file dependent options" dialog by clicking on the 4th icon in the toolbar. There you can select at the top "all water depths", as operator "A under condition B", then you select the "initial water depth" and as condition you specify "<0.01" (no space between < and 0.01). For this you define the variable "water depth where initially dry". Return to the main dialog and now select this variable from the user defined variables list, and visualize it. This shows you the water depth where there was initially no water, e.g. ideal for coastal flooding.
