TOOLS COMMANDS © Fluent Inc., Jul-04 5-1 5. TOOLS COMMANDS GAMBIT tools commands allow you to perform the following types of operations: Coordinate system Size function Turbo Geometry Cleanup Coordinate-system commands allow you to create and work with GAMBIT local coordinate systems. Turbo commands allow you to define and generate turbo profiles and to create turbo volumes. Size-function commands allow you to create and attach size functions to geometric entities as a means to control mesh element sizes for triangular and tetrahedral meshes. The geometry cleanup command provides allows you to identify and automatically fix geometry problems such as very short edges, holes, and sharp angles.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
