Dear All, Can anyone possible send me the interpolatingfunctionanatomy .m file. I have Mathematica 5.0 only. I am running a simulation of chemical kinetics, and need the volume to be changed at each timestep which then scales the concentrations. This means as far as I am aware that I will have to use the EventLocator controller. In my system of dif equations I have X'[t] = (bla bla ... ) V'[t] = (k X[t] ) At each timestep I need to scale X[t] by the ratio of (V[t]/V[t+1]) because V is the volume of the cell that the chemical X is in, and X increases this volume. Therefore, X[t] has to be reduced by a ratio of the previous volume to the current volume. I can only think of doing this by having an event detect when the volume increases by a fixed amount, and catching that event,. and then rescaling X'[t] and restaring NDSolve from there. I think the EventLocator can do this automatically. Is there a better way to do this? Yours ever, Chrisantha Fernando
