Defining a moving region

  1. The whole Sample Cartridge Assembly shall move. Therefore all regions have to be selected.

    Press and hold the CTRL key. Move the mouse pointer to one SCA region after the other and press the left mouse button.

    6 regions will be highlighted in the drawing. If there are less, enlarge the SCA and select the missing regions.

  2. Select Settings > Moving Regions.

    The Moving Regions dialog opens.

    The dialog window indicates 6 region(s) selected.

  3. You have to turn the selected region(s) explicitly into moving regions by checking the Fixed velocity option in the Moving type box.

  4. Next you need to specify a fixed velocity in z-direction. A positive value means that the SCA moves up, a negative value that it moves down.

    You have to specify a velocity in either direction, otherwise the property moving will not be preserved!

    Type -0.0001 in the input field for z-velocity.

    Click on Apply and Close.

  5. Press the left mouse button outside the drawing to cancel the selection of the regions.

  6. Now you can ascertain that all required regions have been defined as moving. This is also an easy way to find out whether moving regions have been defined or not.

    Reopen the Moving Regions dialog by selecting Settings > Moving Regions.

  7. Click on select all moving regions.

    All 6 moving regions should be now highlighted in the drawing. If not, repeat steps 1 to 4.

  8. Click on Apply and Close.

  9. The contact line between the moving region and the fixed region has to get the label “sliding”, if a moving region is in direct contact to a fixed one which should not be distorted (e.g. a sealing). Here there is no such line, so you don't need to specify a label.

Now you are ready to start the computation as described in the tutorial Running a Thermal Analysis (Quick Start).
