Timeints, Livelink Matlab, and Histograms

I'm working on CEM43 calculations, which are given by 1/60 * (0.25+0.25*(T>43[degC]))^(43[degC] - T)).
Ultimately, I want to extract this data for a certain domain and then create a histogram from that data. The challenge is that I cannot create a histogram from mesh data, because the mesh is not evenly spaced. I can let COMSOL create the histogram of the data, but it is very very slow, and tinkering with plot/exporting is painful. Does anyone know some way to either A: export data for a specific domain as an evenly spaced mesh (I could export a uniform grid, but the domain is a complex shape, so that is maybe not the most useful) or B: create a running integral as a dataset which I can work with without evaluating the whole time integral every time I need to plot?
Thanks

1. You can create a running time integral using the Domain ODE and DAE interface. If using a dependent variable (eg T) care should be taken to use a segregated solver.
2. Plots can be exported as uniform grids of specified size, available on the export menu.
