 **2. Using the solver**  
 After the parameters have been defined, the solver can be set up automatically by instantiating the object as,
 ```python
 import dart.api.internal.polar as pol
-polar = pol.Polar(p)
+polar = pol.Polar(cfg)
 # or
 import dart.api.internal.trim as trm
-trim = trm.Trim(p)
+trim = trm.Trim(cfg)
 ```
 The script can then be run by calling,
 ```python
