Channel Flow Simulation using Converge CFD

Objective:

To prepare the Case Setup in Converge Studio,run the case with three different mesh sizes and post process the results using Paraview for a simple box.

Procedure:

Create a simple box from the Geometry dock using the Create option.

2. Flag and designate the boundary regions using the Boundary option.

3. Create the case setup with the required variables shown in the tutorial video.

4. Enter the three different mesh sizes 2e-4m,1.5e-4m & 1.0e-4m in the Base Grid option.

5. Check for any Case Setup issues by using the Validate All option.

6. Export the input files to a designated folder and run the simulation using Cygwin.

7. Convert the output files obtained from the simulation in Paraview.

8. Plot the graph and post process the results.

Results:

The channel flow simulation for a simple box figure is obtained using the above steps and the findings are attached below.
