Complex geometry initial conditions

I want to simulate a realistic dam break case using DualSPhysics and I was wondering if it's possible to create a fillbox that matches a realistic complex geometry?
In other words, can I set a certain water height to fill a complex geometry?



  • Hello,

    You should have a look at TestCase Pump.

  • Please read the documentation first:
    Page 45 of doc/guides/XML_v4.0_GUIDE.pdf
  • Thank you both for the reply.
    I did look into the pump case, and I was aware of the fillbox method. I tried to create the case with the freecad macro and the only problem is that I need to fillbox to rotate for a few degrees to accurately capture the part of the domain that needs to be filled but it seems that rotating isn't an option. I even had the idea to create several smaller fillboxes but it's a big domain.
    It seems that the fillfigure option is the one I need. I shall check it out, shame there isn't an example for it.

    Thank you again and regards.
  • I am not sure that "fillfigure" will work on the GUI with FreeCad.
    It is better if you directly work with modiying the XML

    Just jumping in. Did you get it to work with fillfigure? Would you mind showing a basic example?

    In the end I realized that fillprism would be the easiest way to do it but it was a drag since I had to add a lot of points.
    I studied the fillfigure option through the example in the /doc/xml_format/CaseTemplate.xml
    The code is as follows:

    <fillfigure x="0.1" y="1" z="1.1">
    <point x="0" y="0" z="0" />
    <point x="1" y="0" z="0" />
    <point x="1" y="1" z="0" />
    <point x="0" y="1" z="0" />
    <point x="0" y="0" z="0.8" />
    <point x="1" y="0" z="0.8" />
    <point x="1" y="1" z="0.8" />
    <point x="0" y="1" z="0.8" />
    <triangle x="0" y="1" z="5" />
    <triangle x="1" y="2" z="6" />
    <triangle x="2" y="3" z="7" />
