TEMP2D is a set of MATLAB routines that can be used to calculate the temperature evolution of exhuming rocks in a ramp-flat geometry. The routines must all be placed in a common folder. These routines are: · TEMP2D_Calc.m · TEMP2D_PT_Path.m · TEMP2D_Cooling_Rates.m · function_plot_2d.m · plot_reactions.m and they can be run by typing their names in the MATLAB command window. Together with the previous functions, the file XY_reactions.mat datafile should be in the same folder. The main calculation is done in TEMP2D_Calc that obtains the temperature field using the finite-difference method in 2 dimensions. The code has been written in general form using functions that would allow the more transparent presentation of the results. Other main routines that can be used to plot the results are TEMP2D_PT_Path and TEMP2D_Cooling_Rates. More technical details follow below.
