Hi all, I have a problem I'm trying to solve. I have a code that has written a simple ascii text file like this: write(ilun_out, '(E23.15,A,E23.15,A,E23.15,A,E23.15)' x, ' ', y, ' ', z, ' ', rho So this provides a nice looking ascii file with four columns, separated by a small space. Now...

I see what you're saying, but I have to give this some careful thought. The purpose of doing this is to study the effects of certain modified gravity theories on the baryon density in galaxy clusters... so I can't really ignore gravity. Sadly I'm in a bi of a rush now, but I'll give it some more...

Thanks for the suggestions, in the time after I had first written the original post and you answered I had come across the Method of Charecteristics, and I tried it on the equations posted above. Let me type them up here, as I am not quite sure of how to proceed. EDIT: I seem to have forgotten...

Hi. Since these equations are approaching three hundred years old I'm pretty sure someone must have solved them somewhere before. However I have not been able to find any text-books or papers that actually show me how to solve these equations. So I'm wondering if anyone here know where I can...
