Post-Processing of SMART Output

Option 1 (if only the main result is of interest)Import of BTC data (file <name>.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 <name>.dat into various TecPlot input data files:<name>.cem.dat : includes entire data matrix (x-value, time-value,

all concentration values)<name>.cvt.dat : includes concentrations vs. time data (btcs)<name>.cvx .dat : includes concentrations vs. length data (profiles)

Post-Processing of SMART OutputThe Excel option: an example (source term modelling)

How to do it:1. Open <name>.btc from Ecel2. Add diagram and format it3. Save as excel file

Only the breakthrough curveat the column outlet is plotted
