Various types of elements

Within the Element Browser window double-click onto the EmptyBox to expose the Edit Window of the element (Element Editor). Position the Element Editor window upon to your needs.

Remark: Select Help→Example Load and look for the example file overlap.antherm within the example folder (Beispiele) of the distribution.
The window Element Editor is used to ender and modify properties of one element selected for editing.

Following properties shall be entered:

  • geometrical placement (the coordinates x1,x2,y1,…
  • Element type:
    • EmptyBox – a deletion element
    • MaterialBox – an element filled with material
    • PowerBox – a range covered by a power source
    • SpaceBox – a room (filled with air of constant temperature)
  • optionally: an assignment to a editing group(s)
  • Die Thermal Conductivity (lambda) or Thermal Transfer Coefficient (alpha)
  • optionally: colour for visualization (currently no images nor patterns can be defined)
  • Name of a Space or of a Power Source
Within Element Editor window change the y1 coordinate of the element EmptyBox from  11 to 9.

To accomplish this click onto the input field y1, delete the content by using the Del and/or Backspace key and enter 9.

If the data has not been confirmed yet by leaving the input field, the current input has no influence onto the modelled construction.
Confirm entered data with the TAB key. The change will be visible immediately in all other windows.
Rotate the 3D view by 90° to the left - click onto the window  Elements 3D and while holding the left mouse button pressed over the 3D view move the pointer to the left. In our example (project file "overlap") the EmptyBox extends out of the SpaceBox – we wont to change it now:
Click onto the Element Editor window  (if the Element Editor window is obscured or hidden by other windows, double-click onto the  EmptyBox within Element Browser). You can reveal and activate the Element Editor window by:
  • a double click onto a element within Element Browser
  • via a context menu Edit of the Element Browser - the menu is shown when the right mouse button is pressed.
Within Element Editor use the TAB key to proceed to the input field z1 By pressing the key TAB (or Shift-TAB) you move the input focus between the input and control elements of a window – not only input fields but switches and buttons also.

The exact focus transfer and usage scenarios are described within the documentation of the windows operating system.

For z1 enter 1, press TAB and for z2 enter 9. Press TAB. The change has been applied and made visible immediately in all other windows.
Within the Type field select MaterialBox by choosing that type from the list (or make the selection with up- or down-arrow key). The change has been applied and made visible immediately in all other windows.

The MaterialBox is displayed as solid and opaque object.

During the change of Type other input fields are renamed and activated for the input. The input fields of Lambda and Colour are active now.

Press TAB key to focus onto the input filed Material Name and enter „Material XYZ“. The entry of material properties (Name, Thermal Conductivity, Representation Colour) can be provided directly within the Element Editor window.

Alternatively you could pick material properties from the Material List also  – but within this tutorial we would like to focus on basic data entry methods at first.

With the TAB key move on to the input field Lambda, enter 1 and confirm the input with the TAB key.  
Change the Colour used to display the element - double-click onto the rectangle next to the label Colour: . The standard windows' colour editor will be exposed.
Select the Colour within the Colour window and confirm the choice with a click onto the Ok button. The change of the colour is immediately shown within the graphical view.
   
The Spaces (the boundary conditions)  
Within the Element browser window select the SpaceBox. Double-click onto the SpaceBox to expose the Element Editor window .  
In the input field Surface name enter „Exterior surface“. Analogically to materials the surfaces shall have different properties too.

Akin to material's Thermal Conductivity the surface is described in terms of its Thermal Transfer Coefficient.

Confirm the name entry with a TAB key and enter 10 into the input field Alpha.  
With the TAB key move to the field Space name and enter  „Exterior space“ . All SpaceBoxes are consolidated by their space name to one space. Each such space will be assigned a value of temperature (the boundary conditions).

With consistent assignment of space names – e.g. exterior, living room, kitchen, bath – or – e.g. Room 0, Room 1, … - one creates the list of the boundary conditions for the simulation.

Confirm the entry with the TAB key Changed data is reflected in all windows.
