intro story DELWAQ

DELWAQ

DELWAQ is the engine of the D-Water Quality and D-Ecology programmes of the Delft3D suite. It is based on a rich library from which relevant substances and processes can be selected to quickly put water and sediment quality models together.

The processes library covers many aspects of water quality and ecology, from basic tracers, dissolved oxygen, nutrients, organic matter, inorganic suspended matter, heavy metals, bacteria and organic micro-pollutants, to complex algae and macrophyte dynamics. High performance solvers enable the simulation of long periods, often required to capture the full cycles of the processes being modelled.

The finite volume approach underlying DELWAQ allows it to be coupled to both the structured grid hydrodynamics of the current Delft3D-FLOW engine and the upcoming D-Flow Flexible Mesh engine (1D-2D-3D) of the Delft3D Flexible Mesh Suite (or even other models such as TELEMAC).

'DELWAQ in open source' is our invitation to all leading experts to collaborate in further development and research in the field of water quality, ecology and morphology using Delft3D. Feel free to post your DELWAQ related questions or comments in this dedicated forum space. If you are new to DELWAQ, the tutorial (in the user manual) is a good place to start. A list of DELWAQ related publications is available here.

USB Passthrough not working any longer after most recent Debian Update

I'm utilizing a passthrough arrangement with a Windows 10 VM running on Debian testing which until yesterday worked consummately. In the wake of introducing the week after week refreshes (*1), the VM itself is as yet running fine, nonetheless, USB passthrough (*2) stopped working; great, not totally: The gadgets (BT connector and XBO recipient) actually appear, however Windows Device Manager states "Invalid Configuration Descriptor" and "Invalid Device Descriptor" separately. Quickpayportal Adding the gadgets by means of Spice functions as it did previously, however I'd preferably try not to need to add the Spice worker, regardless of whether the showcase can be set to "None". The main arrangement record that was refreshed during the update was "/and so forth/libvirt/qemu.conf", yet I have just added back all options (client, gathering, some EVDEV arrangement) and all the dynamic alternatives are equivalent to previously. The apparmor config (consistently one of the suspects) didn't change with this update and debilitating it in qemu.conf produces similar outcomes. On the off chance that you have a thought what precisely may have caused the USB passthrough not to work appropriately any longer, any assistance would be generally valued! In the event that your proposal is to go a regulator through, that sadly won't work due to the mobo's crappy IOMMU design and my reluctance to utilize a fixed piece on this specific machine
