SUBROUTINE ReadFromChomboFile(INTEGER nFrame)

Click here to view the Revision 178 source.

Retrieves the data:datatype=0 dataset from the Chombo HDF file indeicated by nFrame and stores it in the current Forest structure. The data is read in level by level and stored in the q arrays of the NodeInfo structures on each level. If the current problem uses MHD, then it reads the MHD_Data dataset into the NodeInfo%aux arrays as well.

ReadChomboFile() reads a file in the out/ directory following the naming convention chomboddddd.hdf, where ddddd is nFrame formatted out to five decimal places (i.e., nFrame = 3 would give us chombo00003.hdf). Note that his function assumes that the current Forest structure in memory identical to the structure that produced out/chomboddddd.hdf, but does not check.

USES:

• mpi_exec.f90 supplies parameter-copying routines for parallel processor mode.
• HDF5 supplies HDF5 API.
• nodeinfodef.f90 supplies the NodeInfo data structure and some functions that operate on it.
• treeops.f90 supplies the Node and Forest structures and accompanying methods, as well as the ApplyOn_ functions.
• problem.f90 Supplies the problem setup data. This file exists in bearclaw/lib, but is superseded by bearclaw/contrib/astro/problem.f90.
