| + | - in 'Tools' >> 'Options' >> 'View', write the path of the Paraview executable in the user computer, e.g. ''C:\Program Files\ParaView 5.6.0-Windows-msvc2015-64bit\bin\paraview.exe'' | ||
| + | - Select a 3D ''.vtr'' file of the simulation output folder and click on the 'Export and open in specific format' button. Choose 'Open File with Paraview' ( Paraview will open automatically.) | ||
| + | - Withing Paraview: | ||
| + | - (The selected file should be automatically highlighted in Paraview.) Click on 'Apply'. | ||
| + | - Other settings: | ||
| + | - Representation: Surface | ||
| + | - Cell/Point Array Status: Choose the array to be displayed. For example, one can display the file ''bandedges.vtr'' and choose the array ''Gamma'' that corresponds to the \Gamma conduction band. Click on 'Apply'. | ||
| + | - Coloring: Choose the array to be displayed. (Gamma, in this example) | ||
| + | |||
| + | Now you can play with the tool rotating, changing opacity and adding filters. | ||
| + | Paraview is a very rich tool: It requires some time to explore all its capabilities. | ||
| + | We recommend investing some time to learn about its filters. First the file should be highlighted and then to click 'Filter' >> 'Alphabetical' | ||
| + | Some interesting ones are: | ||
| + | * Edit cells by region | ||
| + | * Calculator | ||
| + | * Contour | ||
| + | |||
| + | Using 'File' >> 'Save State', the compute can store the value of all variables, to reproduce again the representation, if necessary (by loading the state). This is useful for generation of scripts. | ||
| + | |||
| + | Having more questions, we recommend a good tutorial from TACC, although there exist plenty of examples on the web: [[https://portal.tacc.utexas.edu/c/document_library/get_file?uuid=01dd202d-58c6-4b46-8310-b6d7087372ac&groupId=13601|https://portal.tacc.utexas.edu/c/document_library/get_file?uuid=01dd202d-58c6-4b46-8310-b6d7087372ac&groupId=13601]] | ||
