Upon completing this Tutorial you will understand: ANSYS workbench environment o Create a new project, create geometry, mesh the domain, identify and name boundary conditions, grid adaptation Flow simulation in Fluent o Export mesh to Fluent , apply boundary conditions, iterate toward the solution, examine the flow fields, obtain numerical results, examine and validate the results Project 1 description: Simulate fluid flow through a rectangular channel shown below. Figure Consider air flowing through a rectangular channel of 2cm height and 10cm length.
