Hi All

I just started to learn Dymola, OR Modelica and I installed the demo version from the Dymola website (http://www.3ds.com/products/catia/portfolio/dymola/demo/). Anyhow I started with an example called Pendulum from the Getting Start documentation from the Dymola Demo Version.
The Problem start when I want to Simulate the Model it appears to me this error:
simulateModel("Pendulum", method="dassl", resultFile="Pendulum");
= false
in the Commands Window

The thing is, in Demo Version I am not allowed to simulate a complex system, but I tried even the simplest one and it doesnt work and I mean there is a PROBLEM with my Dymola!!

the Model is:

model Pendulum
parameter Real m=1;
parameter Real L=1;
parameter Real g=9.81;
parameter Real J=m*L^2;
Real phi(start=0.1);
Real w;
equation
der(phi) = w;
J*der(w) = -m*g*L*sin(phi);
end Pendulum;

I will be happy for you answer.

Thank you from help in Advanced
