TCGRID v. 400


TCGRID (Turbomachinery C-GRID) is a 3-D grid generation code for turbomachinery blades. It can generate single or multiblock grids that are compatible with various analysis codes including SWIFT and ADPAC. Single-block grids can be either C-type or H-type, and can be for linear cascades or annular blade rows. Multi-block grids use C-type grids around the blade, and can add an H-grid in the inlet region and O-grids in the hub or tip clearance regions.

Computer requirements

All codes are supplied as Fortran source code and require a Fortran 90 compiler for use. The Cray, Compaq, GNU, Intel, and SGI compilers have all been used successfully. The codes are usually run on Linux systems, butwill run on on a PC or Mac. Parallel processing is available on multi-core computers using OpenMP directives. Check the Fortran Store for information on Fortran compilers

Graphical output

No graphical output is provided with these codes, but access to some CFD visualization software is required to view and evaluate the grids and solutions. Grid and solution files are in standard PLOT3D format and can be read directly and plotted with the public-domain CFD visualization tool PLOT3D, or the commercial tools FieldView, TecPlot, or EnSight CFD. Check the following web sites for information on CFD visualization software.
