====== Materials window ======

This window lists all the [[Material|materials]] of the current [[Model|model]]. To display this window select **Window | Materials** from the [[Menu_bar|menu bar]].
Window is presented as a Tab at the same right bottom part of interface as [[blocks_window|Blocks window]]  and [[scenarios_window|Scenarios window]]. 

[[Material window|{{:materials_window.png?600}}]]

From this view you can:

  * create, edit and delete [[Material|material]] and [[Material|radionuclides]];
  * edit properties of material/radionuclides

By default, this window is divided into five labeled columns indicating material properties: Name, Enabled, Half life, Half life unit and Unit. More properties and options can be made available by clicking the [[Table_control_button|{{:tablecontrol.png}}]] button and selecting the desired property from the menu that appears.

|//Empty//|Displays an error symbol for materials that are missing values or contain errors. You can double click this column to edit a material.|
|Atomic number*|The atomic number of a radionuclide.|
|Author|The "author" of the material.|
|Category|The category of the material.|
|Decay daughters*|The daughter nuclides.|
|Decay parents*|The parent nuclide(s).|
|Decay root*|If checked, the nuclide is the root nuclide in a decay chain (it has no parent nuclide). (Not editable).|
|Description|A description of the material.|
|Editable|Toggles editable on or off.|
|Element*|The atomic element of the radionuclide.|
|Enabled|Enables or disables the material. Disabled materials are not included in simulations.|
|Full name|The full name of the material. For the material "H" the full name would be "Hydrogen".|
|Half life*|The half life of the radionuclide.|
|Half life unit*|The time unit to display the radionuclide half life in.|
|Mass number*|The mass number of the radionuclide.|
|Name|The name of the material.|
|Symbol|The symbol for the material.|
|Unit|For radionuclides, the only available units are Mole and Bq. The decay unit must be the same for all radionuclides. The unit of a material will affect the unit of [[Transfer|transfer]] and [[Compartment|compartment]] blocks.|
|Visible|Toggles visibility (in the Ecolego player) on or off.|

* Only available with the [[Radionuclide_toolbox|radionuclide toolbox]].


|Note|When you disable a [[Radionuclide|radionuclide]] you will also disable all its decay daughters.|

When [[Material|Material]] is selected in [[information_window|Information window]] main information related to the material is shown. 


===== Title bar =====

The title bar has short-cuts for common tasks:

|{{:New24.png}}          |Creates a generic material.                                                                                                                                                      |
|{{:CreateNuclide24.png}}|Adds a radionuclide to the model from the radionuclide database. Note that radionuclide chains must be added from the [[Nuclide_database_window|radionuclide database]].|
|{{:Edit24.png}}         |Opens a dialog window that lets you edit the selected material.                                                                                                                   |
|{{:Delete24.png}}       |Deletes all selected materials from the model.                                                                                                                                   |
