intro story D-Flow FM

 

D-Flow Flexible Mesh

D-Flow Flexible Mesh (D-Flow FM) is the new software engine for hydrodynamical simulations on unstructured grids in 1D-2D-3D. Together with the familiar curvilinear meshes from Delft3D 4, the unstructured grid can consist of triangles, pentagons (etc.) and 1D channel networks, all in one single mesh. It combines proven technology from the hydrodynamic engines of Delft3D 4 and SOBEK 2 and adds flexible administration, resulting in:

  • Easier 1D-2D-3D model coupling, intuitive setup of boundary conditions and meteorological forcings (amongst others).
  • More flexible 2D gridding in delta regions, river junctions, harbours, intertidal flats and more.
  • High performance by smart use of multicore architectures, and grid computing clusters.
An overview of the current developments can be found here.
 
The D-Flow FM - team would be delighted if you would participate in discussions on the generation of meshes, the specification of boundary conditions, the running of computations, and all kinds of other relevant topics. Feel free to share your smart questions and/or brilliant solutions! 

 

=======================================================
We have launched a new website (still under construction so expect continuous improvements) and a new forum dedicated to Delft3D Flexible Mesh.

Please follow this link to the new forum:

Lots of things to consider in Sprint

Lots of things to consider in SprintLots of things to consider
  • Is there a time-critical to it? If GDPR is approaching and your product handles customer data it needs to be done before the law kicks in.
  • Is there a severity criticality to it? If your payments integration is charging double the amount, we first need to get that sorted out.  Before more and more customers start clamoring for refunds.
  • Is there a time dimension involved? We had promised a feature to customer last month and somehow it's still in the backlog. Especially in a B2B scenario, it would be important to adhere to dates because the customer would have lined up other business activities like marketing based on the previously agreed-upon dates.
  • How important is the new requirement for our use case? Maybe we are Facebook and we need to stop all else that we are doing and just do social networking.  If it is a product defining/redefining/business pivot decision from which the new requirement is driven, it makes sense to course-correct immediately.
  • What are the business benefits of doing it immediately? What will I need to postpone doing if I do this immediately? What is the business impact of that postponement? Do the business benefits of doing the change immediately vs what we lose by postponement work out in our favor?
  • Is the feature in the new requirement a must-have for our product that we missed? Are we working on some nice-to-haves that we can look into later? Is the new requirement a mind-boggling feature that we should prioritize over nice-to-haves?
  • Is it even possible to be picked in this Sprint? Does the new requirement need a lengthy setup that it will take beyond this Sprint?
I am also wary of adding members to the development team to get more work done. We literally treat our developers like cattle "Hurr, Hutt". As if they have no thoughts, no freedom. We just "hurr, Hutt" them as it pleases. It just doesn't work. A new joiner will take time to assimilate into the team. He/She will need time to understand the product architecture. By the time all that happens, the Sprint will be over. No logic at all. We treat software development as if it's similar adding one more person to man the call center to handle a spike of incoming calls. But software development is fundamentally different. <!--td {border: 1px solid #ccc;}br {mso-data-placement:same-cell;}-->Devops Online Training

The writer makes a great and articulate point on this website and comparable to the Avengers Jacket article. I really inspired and appreciate him.

The Scrum Master, item proprietor, and advancement group all take an interest. Others may go to on uncommon events when the item proprietor and group both concur it's proper. For instance, if the coming run will incorporate creating usefulness best clarified by a topic master (who isn't the item proprietor), it tends to be helpful to have that individual join in. As a rule, nonetheless, that sort of conversation is best led outside the genuine arranging meeting.https://myaccountaccess.live/
