JINTRAC case

In this example, we will visualize the electron temperature GGD of the edge profiles IDS, as well as the 1D core profiles. We will use the psi grid from the equilibrium IDS to map the 1D electron temperature profiles onto a 2D grid. By doing this, we can visualize the electron temperature both in the edge plasma and in the core in a single image.

You can download the ParaView state file for this example here. However, we recommend that you manually follow the steps outlined below.

Loading the Edge Profiles Electron Temperature

This subsection covers loading and visualizing the electron temperature in the edge plasma region from the edge_profiles IDS data.

  1. Navigate to Sources > IMAS Tools and select the GGD Reader.

  2. Enter the following URI in the Enter URI field of the GGD reader plugin, and press Apply:

    imas:hdf5?path=/work/imas/shared/TEST/simulations/test/8743dad6d7f211ef8fd59440c9e7706c/imasdb/iter/3/53298/2
    
  3. Select the edge_profiles IDS in the IDS/Occurrence dropdown menu.

  4. Select Apply to load the edge profiles GGD grid.

  5. After the GGD grid is loaded, bring the grid into view by aligning the viewpoint in the positive Y direction using the following button: ico1.

  6. Select the Electrons Temperature from the attribute array selection window.

  7. Select Apply to load the electron temperature values on the grid.

  8. Select Electrons Temperature [eV] in the coloring dropdown to visualize the electron temperature.

Loading the Electron Temperature 1d Profile

This subsection covers loading the 1D electron temperature profile, and plotting it in a line chart with the normalized toroidal flux coordinate (rho_tor_norm) on the x-axis.

  1. Navigate to Sources > IMAS Tools and select the 1D Profiles Reader.

  2. Enter the following URI in the Enter URI field of the 1D Profiles reader plugin:

    imas:hdf5?path=/work/imas/shared/TEST/simulations/test/8743dad6d7f211ef8fd59440c9e7706c/imasdb/iter/3/53298/2
    
  3. Select the core_profiles IDS in the IDS/Occurrence dropdown menu.

  4. Select Apply to load the available core profiles.

  5. Select the Electrons Temperature from the attribute array selection window.

  6. Select Apply to load the electron temperature 1D profile.

  7. To plot the 1D profile, we will apply a plotting filter. This can be found under Filters > Data Analysis > Plot Data. Select Apply to apply the filter.

  8. In the filter properties, uncheck Use Index For X Axis and in the X Array Name dropdown select rho_tor_norm. Also uncheck rho_tor_norm from the Series Parameters. You should now have a line chart of the electron temperature with the normalized toroidal flux coordinate on the x-axis.

Loading the Poloidal Flux 2D Profile

This subsection covers loading and visualizing the poloidal flux from the equilibrium IDS to create the 2D plane for mapping 1D profiles.

  1. Navigate to Sources > IMAS Tools and select the 2D Profiles Reader.

  2. Enter the following URI in the Enter URI field of the 2D Profiles reader plugin, and press Apply:

    imas:hdf5?path=/work/imas/shared/TEST/simulations/test/8743dad6d7f211ef8fd59440c9e7706c/imasdb/iter/3/53298/2
    
  3. Select the equilibrium IDS in the IDS/Occurrence dropdown menu.

  4. Select Apply to load the equilibrium 2D profiles.

  5. Select the Psi from the attribute array selection window.

  6. Select Apply to load the poloidal flux values on the grid.

  7. Select Psi [Wb] in the coloring dropdown to visualize the poloidal flux.

  8. Select the 1D Profiles Reader, and select the Grid Psi

Mapping 1D Profiles onto 2D Equilibrium Grid

This subsection covers the mapping of the 1D electron temperature profile onto the 2D equilibrium grid to produce a 2D profile of the electron temperature.

  1. Select the 1D Profiles Reader and apply the following filter: Filters > IMAS Tools > 1D Profiles Mapper.

  2. In the pop-up window, we must select which source contains the psi grid and which contains the 1D profile. So select the 2D Profiles Reader for the psi grid, and the 1D Profiles Reader for the 1D profile. Press OK to confirm the selection.

  3. Select Apply to apply the 1D Profiles Mapper filter.

  4. Select the Electrons Temperature in the Select 1D Profiles selection box. You will now see the 1D profile mapped onto a 2D grid.

  5. Values outside the valid psi range are colored yellow by default, but we can make them transparent instead. To do this, select Edit under the Coloring section and set the Nan Opacity to 0. You should now see that the 1D profile is mapped within the edge profiles of the GGD Reader.

  6. The data sets now have separate color bar ranges, so we can manually set these to the same range. For this, select the 1D Profiles Mapper filter and select the rescale to custom data range button: ico2. Set the range from 0 to 25000.

  7. Repeat the previous step for the GGD Reader, and remove the visibility of one of the colorbars, using the following button: ico3.
