Hi all

I tried to run the example 18_rotor_tower_monopile of WISDEM tutorial from the Python file:

design_run.py

It runs properly, However, the Optimization FAILED due to the Iteration limit reached as shown below:

Although I have increased the number of iterations as follows, again the Optimization FAILED for the same reason:

```
driver:
optimization:
flag: True # Flag to enable optimization
tol: 1.e-6 # Optimality tolerance
max_major_iter: 300 # Maximum number of major design iterations (SNOPT)
max_minor_iter: 1000 # Maximum number of minor design iterations (SNOPT)
max_iter: 10 # Maximum number of iterations (SLSQP)
solver: SLSQP # Optimization solver. Other options are 'SLSQP' - 'CONMIN'
step_size: 1.e-2 # Step size for finite differencing
form: forward # Finite differencing mode, either forward or central
```

What should I do to obtain a successful optimization?
