This input file is the one of the series of three "sample-kits". It concerns the generation of four 3D BFC grids to be fitted with: corrugated circular pipe, helically coiled pipe, snail-like chamber and an igloo object.
The problem is wholly focused on calculation of grid corner coordinates. Therefore, no other functions are supported by input data.
It is arranged as unsteady problem: at each time moment the new BFC grid is PLANTed and dumped into specified file to be viewed by PHOTON.
