At the end of a calculation, STADIUM® creates different output files where the simulation results are written. The main output file has the .xls extension. As shown in Figure 23, the results are written in columns. It is therefore possible to generate graphs from this file by opening it with the appropriate software. The results in Figure 23 were opened with Microsoft Excel. Since the data are written as text in the output files, they have to be converted into columns if Excel is used. This can be done with the data:convert function.

The results from different time steps are separated by a blank line. In Figure 23, this corresponds to line 93. A label at the top of each column indicates its content. The columns are:
§ A: time increment in which the solution will be printed to the output file. To obtain total time, multiply by the time step, in seconds.
§ B: node numbers in the finite element mesh.
§ C: node positions, in cm. This column contains the x-value on most x-y graphs.
§ D – K: concentration of each ionic species, in mmol/L.
§ L: water content in the material, in m3/m3.
§ M: electrochemical potential that enforces the electro neutrality requirement in the material, in Volts.
§ N: temperature in the material, in °C.
§ O– W: content of each of the nine solid phases considered in the calculations, in g/kg material.
§ X: porosity of the material, adjusted for dissolved or precipitated phases at each location, in %.
§ Y: total chloride content in the material, expressed in g/kg dry material.
The other two files contain data from a corrosion analysis performed on a structure. These files have a .cl_tot.xls and a .cl_oh.xls extension. They respectively contain results on total chloride content and chloride/hydroxide ratios calculated at different rebar locations through time as shown in Figure 24. Like the .xls files, they can be opened with Excel to plot the data on an x-y graph. Time, expressed in years, is located in the first column. Each subsequent column contains either total chloride content (in g/kgdry material) or the chloride/hydroxide ratio for a given rebar position.
