Load htc files¶
HTCFile takes the htc-filename and optionally the modelpath as
input.
The modelpath is the path from where HAWC2 should be run, i.e. the
the origion for relative data file paths in the htc file. If not
specified (default) the modelpath is autodetected if possible.
In [2]:
htc = HTCFile(filename=tfp+"htcfiles/DTU_10MW_RWT.htc",
modelpath=None # modelpath autodetected
)
print (htc.modelpath)
C:/mmpe/programming/python/WindEnergyToolbox/wetb/hawc2/tests/test_files/
Access htc contents¶
Access elements(lines and sections) in the htc file via dot or string notation
In [3]:
wsp = htc.wind.wsp # dot notation
print (wsp)
convergence_limits = htc['simulation.convergence_limits'] # string notation with dot
print (convergence_limits)
wsp 4;
convergence_limits 1000 1 1e-07;
you can also store a (sub)section in a varble and access subelements from that
In [4]:
wind = htc.wind
print (wind.wsp)
wsp 4;
Values of a line are obtained by
In [5]:
print (wsp[0])
print (htc.simulation.convergence_limits[:])
4
[1000, 1, 1e-07]
In case there is more than one element with the same name, e.g. main_body sections in new_htc_structure:
In [6]:
htc.new_htc_structure.keys()
Out[6]:
['main_body',
'main_body__2',
'main_body__3',
'main_body__4',
'main_body__5',
'main_body__6',
'main_body__7',
'main_body__8',
'main_body__9',
'orientation',
'constraint']
Then the right element can be access by adding __x (where x is the
section number). The first element can be accessed without __x or
with __1
In [7]:
htc.new_htc_structure.main_body__1 == htc.new_htc_structure.main_body
Out[7]:
True
Another way to access these elements are:
In [8]:
htc.new_htc_structure.get_subsection_by_name('shaft')
htc.new_htc_structure.main_body(name='shaft')
Out[8]:
<wetb.hawc2.htc_contents.HTCSection at 0x1ff94e5eb50>
HTC Section¶
In [9]:
section = htc.new_htc_structure.main_body__3.c2_def
print(section.section_name)
print(section.keys())
print(section.parent.section_name)
print(section.parent.location())

;----------------------------------------------------------------------------------------------------------------------------------------------------------------
In case there is already one line with the same key, then you need to
use the add_line function

Modify htc contents¶
In [18]:
htc.wind.wsp = 12 # set single value element
print (htc.wind.wsp)
c2def = htc.new_htc_structure.main_body__3.c2_def
c2def.section_name = "c2_def_new"
c2def.sec__4 = 1,2,3,4 # set element with four values
c2def.sec__4[3] = 9
print (c2def)
wsp 12;
begin c2_def_new; Definition of centerline (main_body coordinates)
nsec 5;

sec 2 0 0 1.5 0;
sec 3 0 0 3 0;
sec 1 2 3 9; Main bearing
sec 5 0 0 7.1 0; Rotor centre
end c2_def_new;
Note, that you cannot change modify values of the current line, e.g.
line = htc.new_htc_structure.main_body__3.c2_def.sec__4
line = 1,2,3,4
as it will overwrite the variable line with the tuple (1,2,3,4)
instead of updating the values
Delete¶
Sections and lines are deleted by calling their delete method
In [44]:
htc.simulation.my_line.delete() # second my_line (my_line__2) remains
htc.simulation.my_section.delete()
print (htc.simulation)

;----------------------------------------------------------------------------------------------------------------------------------------------------------------
HTC functions¶
set_name()¶
The set_name function sets the filename, as well as the
log filename
animation filename
visualization filename
output filename (only first output section)
In [45]:
htc.set_name(name="new_name", subfolder='my_folder')
print (htc.filename)
print (htc.simulation.logfile)
print (htc.output.filename)
c:/mmpe/programming/python/windenergytoolbox/wetb/hawc2/tests/test_files/htc/my_folder/new_name.htc
logfile ./log/my_folder/new_name.log;
filename ./res/my_folder/new_name;
set_time()¶
The set_time(start=None, stop=None, step=None) function sets the
start, stop and step time if specified:
In [46]:
htc.set_time(10,20,.1)
print (htc.simulation.time_stop)
print (htc.simulation.newmark.deltat)
print (htc.wind.scale_time_start)
print (htc.output.time)
time_stop 20;
deltat 0.1;
scale_time_start 10;
time 10 20;
simulate()¶
The simulate(exe) function saves the htc file, performs the
simulation using the specified exe (HAWC2), raises an error if the
simulation fails and returns the console output and log
stdout, log = htc.simulate("<path_to_hawc2>\hawc2mb.exe")
Parameter study¶
HTC files for parameter studies, can be generated by a loop that updates the desired values of the htc and saves the result:
In [49]:
from wetb.hawc2 import HTCFile
from wetb.hawc2.tests.test_files import tfp
htc = HTCFile(tfp + "htcfiles/DTU_10MW_RWT.htc")
for wsp in [4,6,8]:
htc.wind.wsp = wsp
htc.set_name("case_wsp%d"%wsp)
htc.save()
HAWC2InputWriter¶
An easier way for more complicate studies is to use the HAWC2InputWriter which takes a case as input (see Case list generation)
A case is dictionary of (key,value)-pairs. Keys can be:
Htc address, e.g. wind.wsp
Function name, e.g.
wspin which casevalueis passed to theset_wspofHAWC2InputWriter(which you must implement)A tag that is replaced by
value
Note, all three types can be combined
First we create the htc file that we want the parameter study to be based on
In [50]:
%%writefile "tmp/base.htc"
begin simulation;
time_stop 600;
logfile log.txt

Writing tmp/base.htc
htc address¶
For (key-value) cases where the keys are htc addresses, we just need a
HAWC2InputWriter
In [51]:
from wetb.hawc2 import HTCFile
from wetb.hawc2 import HAWC2InputWriter
h2writer = HAWC2InputWriter(base_htc_file='tmp/base.htc')
that allow us to make a case like this
In [53]:
h2writer('tmp/my_case.htc', **{'wind.wsp':12, 'simulation.logfile': "my_case.log"})
In [55]:
print (HTCFile('tmp/my_case.htc'))
begin simulation;
time_stop 600;
logfile my_case.log;
end simulation;
;
begin wind;
wsp 12;
end wind;
exit;
Function name¶
For (key-value) cases where the keys are function names, a subclass of
HAWC2InputWriter with the required functions must be implemented:
In [56]:
class MyInputWriter(HAWC2InputWriter):
def set_wsp(self, htc, wsp, **_):
htc.wind.wsp = wsp
bs = self.begin_step
for i, o in enumerate([0,50],1):
htc.wind.add_line("wind_ramp_abs", [bs+o, bs+o+1, 0, 1], "wsp. after the step: %d.0"%(wsp+i))
# ...
def set_log(self, htc, log, **_):
if log:
htc.simulation.logfile = log
else:
htc.simulation.logfile.delete()
This approach enables
Multiple values, e.g. wind speed, turbulence grid size, wind ramp etc., can be set by one (key,value)-pair
Lines or sections can be deleted
Use of constants (specified when creating the writer)
Modification of e.g. aerodynamic, profile or structural data files
In [57]:
h2writer = MyInputWriter(base_htc_file='tmp/base.htc',
begin_step=100, # constant need in the implemented functions (specify as many as you want)
)
h2writer('tmp/my_case.htc', wsp=12, log=None, sensor_y=[10,20])
In [58]:
print (HTCFile('tmp/my_case.htc'))
begin simulation;
time_stop 600;
end simulation;
;
begin wind;
wsp 12;
wind_ramp_abs 100 101 0 1; wsp. after the step: 13.0
wind_ramp_abs 150 151 0 1; wsp. after the step: 14.0
end wind;
exit;
Tags¶
The tag options offers template rendering via the jinja templating language. Jinja templates allows:
variable substitution,
wsp {{wsp}}
conditionals
{% if logfilename %}
logfile {{logfilename}}
{% endif %}
loops
{%- for y in sensor_y %}
wind free_wind 1 0.0 {{ y }} -119;
{%- endfor %}
let us make a new template.htc
In [60]:
%%writefile "tmp/template.htc"
begin simulation;
time_stop 600;
{% if logfilename %}
logfile {{logfilename}}
{% endif %}
end simulation;
;
begin wind;
wsp {{wsp}};
{%- for i in range(2) %}
wind_ramp_abs {{begin_step+i*50}} {{begin_step+i*50+1}} 0 1; wsp. after the step: {{wsp+i+1}}
{%- endfor %}
end wind;
exit;
Writing tmp/template.htc
In [61]:
h2writer = HAWC2InputWriter(base_htc_file='tmp/template.htc')
h2writer('tmp/my_case.htc', wsp=12, log=None, begin_step=100)
In [62]:
print (HTCFile('tmp/my_case.htc'))
begin simulation;
time_stop 600;
end simulation;
;
begin wind;
wsp 12;
wind_ramp_abs 100 101 0 1; wsp. after the step: 13
wind_ramp_abs 150 151 0 1; wsp. after the step: 14
end wind;
exit;
Case list generation¶
The HAWC2InputWriter can also handle a list of cases.
These cases can be defined in a Pandas DataFrame or an excel sheet
Note, case lists must contain a Name column
Pandas Dataframe¶
In [63]:
import pandas as pd
df = pd.DataFrame({'Name':['case10', 'case12'], 'wsp':[10,12], 'log':['','log.txt']})
df
Out[63]:
| Name | wsp | log | |
|---|---|---|---|
| 0 | case10 | 10 | |
| 1 | case12 | 12 | log.txt |
In [64]:
h2writer = MyInputWriter(base_htc_file='tmp/base.htc',
begin_step=100, # constant need in the implemented functions (specify as many as you want)
)
h2writer.from_pandas(df)
h2writer.write_all(out_dir="tmp")
Generating 2 htc files in directory: tmp
In [65]:
print(HTCFile('tmp/case10.htc'))
begin simulation;
time_stop 600;
end simulation;
;
begin wind;
wsp 10;
wind_ramp_abs 100 101 0 1; wsp. after the step: 11.0
wind_ramp_abs 150 151 0 1; wsp. after the step: 12.0
end wind;
exit;
In [66]:
print(HTCFile('tmp/case12.htc'))
begin simulation;
time_stop 600;
logfile log.txt;
end simulation;
;
begin wind;
wsp 12;
wind_ramp_abs 100 101 0 1; wsp. after the step: 13.0
wind_ramp_abs 150 151 0 1; wsp. after the step: 14.0
end wind;
exit;
Excel¶
Saving previous dataframe as Excel spreadsheet
In [69]:
df.to_excel('tmp/caselist.xlsx', index=False)
which can be opened and modified in Excel
In [70]:
# uncomment to open in excel
# %system "tmp/caselist.xlsx"
Loading case list from (modifyed) excel sheet and write htc files
In [71]:
h2writer.from_excel('tmp/caselist.xlsx')
h2writer.contents
h2writer.write_all('tmp')
Generating 2 htc files in directory: tmp
Design Load Basis (DLB)¶
The DTU_IEC64100_1_Ref_DLB can make a case list covering a subset of
the full DLB as defined in IEC64100-1(2005).
Note, some DLCs are missing.
Some interpretation are made see Hansen, M. H., Thomsen, K., Natarajan, A., & Barlas, A. (2015). Design Load Basis for onshore turbines - Revision 00. DTU Wind Energy. DTU Wind Energy E, No. 0074(EN)
In [72]:
