 ===== Dam Break ===== ===== Dam Break =====
-This is one of the most simple cases to create. It will create a cube of water spreading out in a box. The result should be like this:+This tutorial creates a basic body of water that simply falls and fills its encasing. It'​s ​one of the most simple cases to do, and is recommended to learn the basics.

-This simulation consists in a 1 meter * 0.5 meter roofless box that contains ​a resting ​body of water in a shape of a cube, that will fall to the floor once the simulation starts.+===== Float example ===== 
 +This tutorial creates ​a floating cube falling into a body of water inside ​a case. It uses floating properties.
  
-These are the steps to get to that.+[[float-example|You can view it here]]
  
-==== Step 1 - Creating a new case ==== +===== Initials example ===== 
-First of all, lets run FreeCAD ​and run this software. Make sure VisualSPHysics for FreeCAD is installed. For that, you can check the [[installation|installation page]].+This tutorial includes importing an external mesh (in STL) and placing a body of water in it. It shows how to apply an initial velocity vector to a body of water.
  
-Once in VisualSPHysics for FreeCAD, use the New Case button to create a new case. If you have opened FreeCAD files, VisualSPHysics will prompt you to close them automatically. +[[initials-example|You can view it here]]
- +
-Once created you should see something like this: +
-{{ ::case-limits.png?​300 ​|}} +
- +
-This red lines represent the Case Limits, in which elements that are part of the simulation will be contained. +
- +
-Make sure your plugin is configured correctly, pressing "Setup Plugin"​ and establishing the proper executables in the configuration window that appears. +
-==== Setting the Inter-particle distance ==== +
-Change the Inter-particle distance text input box to **0.025**. It will look something like this: +
- +
-{{ ::​dp-set.png |}} +
- +
-This will set the case to generate a particle every **0.025** meters. For this case is an appropiate value for quick-simulation. +
- +
-==== Adjusting the case limits and creating the boundaries ==== +
-The next step is to adjust the case limits. We need to make the case limits at least be 1 meter on the X axis, and 0.5 meters in the Y axis. So let's do that. +
- +
-First of all select Case_Limits from FreeCAD'​s combo view. You will see the FreeCAD objects properties in the properties table. There, edit the Length, Width and Height to match **1 meter, 0.5 meters and 0.7 meters** respectively. It should look like this: +
- +
-{{ ::​case-limits-size.png |}} +
- +
-Once done that, we will create the boundaries. To create a wall (or a floor), just create a box and fill it with the appropiate parameters in the FreeCAD properties table. Create 5 boxes with this properties +

-**LargeWall1**:​ +
-  * Length: 1m +
-  * Width: 10mm +
-  * Height: 0,5m +
-  * Position (x, y, z): 0 mm, 0 mm, 0 mm +
- +
-**LargeWall2**:​ +
-  * Length: 1m +
-  * Width: 10mm +
-  * Height: 0,5m +
-  * Position (x, y, z): 0 mm, 0,49 m, 0 mm +
- +
-**ShortWall1**:​ +
-  * Length: 10 mm +
-  * Width: 0,5 m +
-  * Height: 0,5 m +
-  * Position (x, y, z): 0 mm, 0 mm, 0 mm  +
- +
-**ShortWall2**:​ +
-  * Length: 10 mm +
-  * Width: 0,5 m +
-  * Height: 0,5 m +
-  * Position (x, y, z): 0,99 m, 0 mm, 0 mm  +
- +
-**Floor**:​ +
-  * Length: 1 m +
-  * Width: 0,5 m +
-  * Height: 10 mm +
-  * Position (x, y, z): 0 mm, 0 mm, 0 mm  +
- +
-Now select all of them in the Combo view (Control + Click each one) and press "Add all possible to DSPH Simulation"​ In the DSPH Object Properties. +
- +
-Now, for each one of them, press in it and c**hange the property MKBound to 0**, as we want all the boundaries to be part of the same object (a external case). You should see that the type of object is bound by default. +
