I want to know that it if I can use FreeFEM to solve a simple ODE. Such as:

```auto
dx/dt=[sin(x1)+x2,cos(x2)]

```

I have searched on the Internet but didn’t find any topics about ODE solving in FreeFEM.

Sorry FreeFem++ is not build to solve ODE  
You have to write you approximation script (use python on math lab).
