Flow-3D Ship Stable

Start EnSight 10

wpid2361-media_1338930554529.png

Double clicking on the EnSight 10 icon or using the command window.

Load Flow-3D Data

wpid2362-media_1338930619443.png

File > Open will bring up the above Open Dialog. Navigate to where your instructor has placed the ship_stable dataset directory (for example, as shown below).

wpid2363-media_1338930736778.png

Select the flsgrf.dat file in the list of files.
This will load the file name and path into the “Set flsgrf” field as shown above, and EnSight will detect that this is FLOW3D data and select the format for you. Instructions and details will be shown in the Comments field.

To include the ship and not just the water surface…
Select Advanced Interface
Then select Format Options, Load internal STL > Restart Timeline
This last step is to bring in the ship which is stored by FLOW-3D as a STL geometry in the result files, and the method.
Click “Load all parts”

wpid2365-media_1338930807387.png

EnSight will load all the parts and the scene will look somewhat like above.

Notice that a default of EnSight is to show you the latest timestep available. This can be changed in the preferences.

Change Timesteps

wpid2366-media_1338931853429.png

To change the timestep shown, just click the left pointing arrow (left button) or just type a value in the Cur (current) field, for example 0 (zero).

wpid2367-media_1338931983341.png

Now the time planel indicates that Beg (beginning) is 0 and Cur (current) is 0 and the ship is sitting upright in the center of the model.

Changing timesteps is a simple as manipulating the time panel controls. There is some delay as EnSight has to fetch the new data and load it.

Create the water surface from an Isosurface

wpid2368-media_1338933064195.png

Right-click on the Block 1″ part in the Parts Panel
From the drop down menu that appears …
Select Isosurfaces…

wpid2369-media_1338933238950.png

Type “Water” in the top field of the Isosurfaces dialog
Select “Fluid_Fraction_Restart” from the Variable list

At the bottom of the dialog select “Create with selected parts”. This refers to to the fact that we used the “Block 1″ part to start this process and so the “Block 1″ part will be the parent part for the isosurface. In many cases for a CFD model in EnSight the parent part should be the fluid domain. An exception would be when you want to create vector arrows on a clip plane, in that case then the clip plane would be your parent part.

wpid2370-media_1338933461754.png

The scene will look like above with the while or light grey isosurface.

Color the Isosurface by a Variable

wpid2371-media_1338933520160.png

Right-click on the isosurface (white plane around the red ship)

In the context menu select “Color by” and in the submenu “Select variable”

 

wpid2372-media_1338933704731.png

Select the variable you want to color by from the list of scalars or vectors.
For example, select “Velocity_Depth_Avg_Restart” from the list of scalars. Click OK

wpid2373-media_1338933882922.png

Change the timestep using the Time Panel controller to the timestep 7 to replicate the scene above.
