Tutorial: How to make internal model "without modeling"??

Tutorial by Aldin Ramic
Small

For example, this can be used for:
-in sand casting, when u have a model like this pump, and we need to have the inner core...
To get a more accurate model of the internal geometry, main model must be more accurate, I mean on the draft angle during the creation of a model ...
Ok, this is it, enjoy...

  1. Step 1:

    1)
    Here is a model of centrifugal pump housing, can be found here: Centrifugal pump housing
    For this model i use some trick how to get a internal geometry (3D model)

  2. Step 2:

    2)
    All you need to do on this model is to close all openings, like to the picture...

  3. Step 3:

    3)
    In the Flow Simulation feature, first click check geometry, than fluid volume...
    Fluid volume will be calculated...see on the pics

  4. Step 4:

    4)
    Check the Create fluid body assembly, and than click check...

  5. Step 5:

    5)
    Here is a result...this is a PART...remember its created by fluid inside housing.. ;)

  6. Step 6:

    6)
    Some renderings...

  7. Step 7:

    7)
    another one render...
    enjoy
