Center for Applied Geoscience - Chair of Applied Geology Research Center at the University of Tübingen Main Output File.dat 2nd part: simulation results Mass input Mass output Mass in column Concentrations as defined in output control section in main input file Indices of contaminant, litho-component, and grain size class Concentration values in each of the model cells Each time step has ist own section

Center for Applied Geoscience - Chair of Applied Geology Research Center at the University of Tübingen Post-Processing of SMART Output Option 1 (if only the main result is of interest) Import of BTC data (file.btc) into Excel Option 2 (if further insight into development in column is wanted) Use of smart2tp (SMART to TecPlot): program converts main output data.dat into various TecPlot input data files:.cem.dat:includes entire data matrix (x-value, time-value, all concentration values).cvt.dat:includes concentrations vs. time data (btcs).cvx.dat:includes concentrations vs. length data (profiles) Available options

Center for Applied Geoscience - Chair of Applied Geology Research Center at the University of Tübingen Post-Processing of SMART Output The Excel option: an example (source term modelling) How to do it: 1. Open.btc from Ecel 2. Add diagram and format it 3. Save as excel file Only the breakthrough curve at the column outlet is plotted

Center for Applied Geoscience - Chair of Applied Geology Research Center at the University of Tübingen Post-Processing of SMART Output Plotting with TecPlot: an example (source term modelling) Labels are automatically generated Layout has to be defined by the user in TecPlot BTCs for different locations in the column (as specified by the user using smart2p)
