Calculate
In ‘Run Calculation’
– press ‘Check Case...’
see ‘No recommendations to make at this time’
– set ‘Number of Iterations’ to 200
– press ‘Calculate’
OK to ‘Continue after replacing settings file’
Problem setup has changed the mesh – for example, the coordinates changed by scaling. There are many other changes that FLUENT can make – for example, adapting the mesh to increase the number of cells where the solution requires it.
The link from Mesh to FLUENT in Workbench needs care – are you starting a new Problem Setup with a new mesh, or are you finding a new Solution on the old mesh?
Calculating
Preliminary post-processing
In ‘Graphics and Animations’, select Contours, press ‘Set Up...’
– select ‘Filled’ contours of ‘Turbulence...Wall Yplus’ on ‘wall-fluid’
– press ‘Display’ – note almost all values are between 30 and 200
Check mass and heat balance
In ‘Reports’, select ‘Fluxes’ and press ‘Set Up...’
– compute ‘Mass Flow Rate’ and ‘Total Heat Transfer Rate’
for inlets and outlets – check that ‘Net Results’ are small
Exit FLUENT
Exit FLUENT
– accept the default, ‘Continue without saving’
In Workbench, double-click ‘Results’ to launch CFD-Post
– in the FLUENT session, we have completed Setup and Solution
CFD-Post
The results are loaded
CFD-Post displays the outline (wireframe) of the model
– viewer toolbar buttons allow you to manipulate the view
Temperature contour plot
Press the contour button
– accept the default name ‘Contour 1’
– select ‘Location’ to be ‘wall fluid’, and ‘Variable’ to be ‘Temperature’
– press ‘Apply’
