Just curious: Has anyone developed a user-friendly utility for placing refined grids for Carpet?
I'm imagining writing a little "drawing" program which will allow the user to draw rectangles to place grids, and then it would generate the CarpetRegrid::coordinates lines for a parameter file.
But I don't want to reinvent the wheel if someone's already done something similar.
Thanks, Scott

It depends what you want. There is afaik no gui. A lot of people use CarpetRegrid2, which allows to specify a number of points around which you want to have a certain number of refinement level of a given size. I believe those parameters are steerable, so that you can adapt this to your specific needs on the go.

To avoid confusion: CarpetRegrid2's parameters are not steerable (to my best knowledge). Instead you have to change grid scalars (see CarpetRegrid2's interface.ccl) during evolution to move the boxes around. The toolkit has thorns for this (CarpetTracker in combination with NSTracker or PunctureTracker). CarpetRegrid's parameters were steerable however.
