# Load 2D diagnostics

To load 2D diagnostics files, you must first have a completed 2D or 1D-2D linked simulation. Depending on the file type chosen, these will open directly in the **Map** view of the interface, within Excel, or within a text editor.

This functionality enables you to quickly and easily investigate diagnostics and troubleshoot issues.

Note:

Selected diagnostic information can also be viewed when you [load 2D results](/v1/docs/how-to-load-2d-results).

### Steps

1. In the **Simulations** section of the **Project** panel, select the simulation name.
2. Right-click and navigate to **Load Diagnostics** to open a further menu.
3. Select from the eight options provided:
  1. **Load cell status check grid(s)** - loads check grids immediately into the **Map** view and the **Layers** panel. The cell status check grid is a particular type of check grid that details the status (boundary/active/inactive) of each cell in the domain. It has its own predefined colour ramp which will be applied automatically upon loading. In a multi-domain model, each domain will have its own cell status check grid.
  2. **View 2D log file** - opens the diagnostics in your native text editor, e.g. Notepad.
  3. **Load all check grids** - opens a window to select from all available check grids, such as ground elevation and initial water depth, for each domain. Check the ones of interest and then click **OK** to load into the **Map** view and the **Layers** panel.
  4. **Load spatial diagnostics data** - loads the shapefile into the **Map** view and the **Layers** panel. Viewing the shapefile attributes provides additional details from each point displayed on the map, including any error messages and the phase (build or run) where this occurred.
  5. **Load z-mod check files** - loads two files into the **Layers** panel; the ztrp file showing points where elevation data has been added, and the ztra file showing the triangulation of your z-mod features. Note that these file types are only applicable if the simulation contains z-mod (elevation modification) features.
  6. **View simulation summary spreadsheet** - opens the file in Microsoft Excel. Note that this will only be possible if you have chosen to [save the simulation summary](/v1/docs/how-to-save-simulation-summary-output-data-2) prior to running the simulation.
  7. **View 2D mass balance file(s)** - opens the mass balance files in Microsoft Excel.
  8. **View 1D linked flow summary file(s)** - opens the linked flow summary file in Microsoft Excel. Note that this file type is only applicable if the simulation is a linked 1D-2D simulation.
