Exporting Quickin file (.dep-file) for a following simulation - Forum - Delft3D Flexible Mesh

Hello Everyone,

I am working on a project for which I have to simulate three years of hydrodynamical and morphological development in an open river flow. Since some geometrical data/barriers (implemented via a *.bar-file) change every couple of weeks i am working with multiple simulations using the restart-file of the previous simulation. However, I checked the morphology development and it seems to me that the restart file does not contain any bathymetry information of the previous simulation.

With Quickplot I can export the 'bed level in water level points' at the end of the simulation and use the exported file as the bathymetry file for the next simulation. But since the bathymetry for the computation is defined negative in the upper direction I need to change the orientation of the bathymetry data. I can either do that using Quickin (operations -> combine depth and uniform value -> multiply depth and uniform value -> -1) OR I can directly export a negative Quickin file. However, when I directly export a negative Quickin file (-Quickin) the default value of -999 is also changed to +999. Thus, using the exported file as the bathymetry file for the next computation doesn't work because when I try to run the simulation +999 is not regarded as a default value but as bathymetry data, which is false and obvioulsy does not work with the simulation.

This doesn't happen when I manually change the orientation of the file. But it would be resonably faster only having to export the file and using it right away.

Is there any way around the manually changing method? Any way I can directly use the exported *.dep-file for the next simulation?

Thank you for your help.
