IMAS_REF_SHOTsets the reference shot number in the IMAS database for data input
IMAS_REF_RUNIDis IMAS reference runid
IMAS_REF_RUNIDinput variable is non-optinal. If the variable is not set, IMAS will not be used to set TRANSP input. The
IMAS_REF_SHOTinput is optional. If this input is not set, the default shot number for a particular TRANSP run will be used.
The TRANSP code has one non-optional input
IMAS_OUT_RUNID, which sets the runid of TRANSP IMAS output. It is strongly recommended to use a different runid that is set for the TRANSP input with the input
The are two optional arguments that are shared between trdat and TRANSP. These variables are
IMAS_BACKENDcan be set to HDF5 (default), MDSPLUS, or ASCII (not recommended)
IMAS_USERsets the username for the IMAS input and output
IMAS_USERinput is the current username. This input is also used to control the input/output directory. If this input is set to a username, the TRANSP will read/save data to the directory ~[username]/public/imasdb/. This directory needs to exist with appropriate permissions for input and output. If
IMAS_BACKENDis set to HDF5, the
IMAS_USERcan be set to any location on current machine that exists and has correct read/write permissions. The TRANSP simulations running on the transpgrid production system at PPPL use different usernames from the usernames who submit TRANSP runs. Since the users don't have access to the transgrid accounts,
IMAS_USERinput needs to be set to the PPPL usernames or to specific directories when HDF5 backend is used.
