• Navigate to your project folder.

• Go to the RESULT folder and choose xy-naturalconvection...vtm. Click OK

• Click in the Properties Panel, on the bottom left.

• Choose variable T from the drop-down list. (See Figure 6.5). This shows the temperature
distribution along the domain.

• Clicking the rainbow button on the left shows the Legend. Clicking the double-arrow button
on its right rescales the color range to the data range.

• See Figure 3.7 for the steady state result of the temperature profile.

• To visualise the converged results, go to the last frame by hitting in the toolbar.
To get a rough idea about visualisation of TransAT results with ParaView, please refer to the
TransAT Paraview Tutorial .

More detailed information can also be found in the Paraview Tutorial on the ParaView website.
