How to run dynamic analisys?

[junjihan]

Dear RAFT developers and lovers：
I write a code accroding to https://openraft.readthedocs.io/en/latest/starting.html Getting Started→Example
as followed:
import raft
import yaml
import matplotlib.pyplot as plt
plt.switch_backend('TkAgg')
with open('VolturnUS-S_example.yaml', 'r', encoding='utf-8') as file:
design = yaml.load(file, Loader=yaml.FullLoader)
model = raft.Model(design)
model.analyzeUnloaded()
model.solveEigen()
model.analyzeCases(display=1)
model.plotResponses()
model.plot()

plt.show()

code results:

However,when I try to run dynamic analysis according to runRAFT.py:

--- Create and run the model ---

model = raft.Model(design, w=w, depth=depth)  # set up model

model.setEnv(Hs=8, Tp=12, V=10, Fthrust=float(design['turbine']['Fthrust']))  # set basic wave and wind info

model.calcSystemProps()          # get all the setup calculations done within the model

model.solveEigen()

model.calcMooringAndOffsets()    # calculate the offsets for the given loading

model.solveDynamics()            # put everything together and iteratively solve the dynamic response

model.plot()

plt.show()

return model 

and I copy
'model.solveDynamics()
model.calcMooringAndOffsets()'to my code:
import raft
import yaml
import matplotlib.pyplot as plt
plt.switch_backend('TkAgg')
with open('VolturnUS-S_example.yaml', 'r', encoding='utf-8') as file:
design = yaml.load(file, Loader=yaml.FullLoader)
model = raft.Model(design)
model.analyzeUnloaded()
model.solveEigen()
model.solveDynamics()
model.calcMooringAndOffsets()
model.analyzeCases(display=1)
model.plotResponses()
model.plot()

plt.show()
it failed:

Could you please tell my how to run dynamic analysis?
