| 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.

| - | ==== Creating the fluid ==== | ||
| To create the fluid the first we're going to do is hide one of the faces in FreeCAD, to see better what is inside the box we've created. To do this select the face you want to hide and press space, or right click -> toggle visibility (this does nothing to the scene or simulation). I chose **LargeWall1** to do this. | To create the fluid the first we're going to do is hide one of the faces in FreeCAD, to see better what is inside the box we've created.

| + | ==== Final Step: Simulating and exporting ==== | ||
| + | You can now save your project. This will generate a GenCase export and tell you how many particles you have to simulate. | ||
| + | |||
| + | From there you can just select your preferred processor in the simulation group (CPU or GPU[Nvidia only]) and press "Simulate Case". Once finished you can export the data to VTK with the button "Export data to VTK". | ||

| + | To see the resulting animation you can open all the data generated with a visualization software, like Paraview. Your simulation data is in the folder you saved the project, under [project name]_Out/ | ||
