Hello PTC Community,
I have problems solving a system of 5 differential equations simultaneously by using ODESOLVE in Mathcad Prime 2.0. I tried other solvers too, but i have the most experience with odesolve. I just don't get the solver to work, no matter what I do. Could you please take a look at my file and tell me, if I have some Syntax-mistakes or anything like it.
The equations should be able to calculate the dispersion of gas, leaking out of a ruptured vessel in a cylindric form.
u represents the speed of the flowing gas
b is the radius of the cylinder
Theta is the angle between the direction of the gas and the horizon
c is the concentration of the leaking gas
T is the temperature of the flow
All those five dependent varibles depend on the independant variable sL, which represents the distance of the center of the cylindric flow to its origin at the ruptured vessel.
Am i maybe using the wrong solver? Any help or suggestions are greatly appreciated.
Tim
