DSM2 - How to read hdf5 output files

DSM2 writes output in HDF5 format. This format can be read by Vista and vscript 

Step-by-step guide

To open a HDF5 file

1. Open Vista 
2. Drag and drop or use Session > Open > Tidefile from the menu options
3. Select the data items needed and use the  Data > Export > Export Data To DSS menu item to export the Data to DSS files

Alternatively here is a snippet of vscript code that does something similar

Getting average concentrations from Qual HDF5 file

from vtidefile import opentidefile
from vdss import writedss
from vutils import *
import vdisplay
from vdisplay import plot
import sys
import string

def get_avg_conc(tidefile, chan, twstr):
    tf=opentidefile(tidefile)
    if twstr != None:
        print 'Timewindow: %s'%twstr
        tw=timewindow(twstr)
    else:
        tw=None
    refs=tf.find(['','^%s$'%chan,'AVG CONC'])
    if refs and len(refs)==1:
        print "Getting data %s"%(str(chan))
        if tw!=None:
            ref=DataReference.create(refs[0],tw)
        else:
            ref=refs[0]
        return ref.data
    else:
        raise "No data found for %s in file %s"%(chan, tidefile)
if __name__ == '__main__':
    if len(sys.argv) != 2:
        print "Usage: vscript 
    tidefile=sys.argv[1]
    twstr="01JUL2014 0000 - 01AUG2014 0000"
    chans=[291,290,436,435,434,433]
    chan_concs=[]
    for chan in chans:
        chan_concs.append(get_avg_conc(tidefile, chan, twstr))

    for conc in chan_concs:
        plot(conc)

DSM2-vista also supports export data to hec-dss format (One or multiple timeseries path could be selected) See the following menu option as example.
