I'm trying to call a python function from within a Tecplot macrofunction.
The main goal is to call a python function and pass it the loop indices for a nested loop that I have, and have the python script go to a file and retrieve an entry based on those two parameters i.e. value = my_python_script(loop_1_index,loop_2_index)
I'm trying to put something together based on the following forum posts:

The relevant part of my macrofunction code is:
Code: Select all
#Get the mean value
$!EXTENDEDCOMMAND
COMMANDPROCESSORID= "Python Utility"
COMMAND='MODIFYPATH FOLDER' = "|PythonPath|"
$!EXTENDEDCOMMAND
COMMANDPROCESSORID= "Python Utility"
COMMAND='RUNPYFUNCTION MODULE="compute_fluctuation" FUNCTION="compute_fluctuation_module" ARGUMENTS="|VarName|,|TimeLoopIndex|,|LOOP|"'
My Python script looks like:
Code: Select all
def compute_fluctuation_module(var_name,loop_index,slice_index)
import TecUtils
import TecVals
#Locate mean value from users inputs
input_file_name = var_name + "_"+loop_index+".txt"
line_count = 1
with open(input_file_name,'r') as f:
for Line in f:
if line_count == slice_index):
mean_value = f.readline()
else:
line_count = line_count + 1
{p_prime} = {p} - 100000'
equation_string = "{"+var_name+"_prime} = "+"{"+var_name+"} - "+mean_value
TecUtil.DataAlter(equation_string)
return
Tecplot complains that: COMMAND='RUNPYFUNCTION MODULE="compute_fluctuation" FUNCTION="compute_fluctuation_module" ARGUMENTS="|VarName|,|TimeLoopIndex|,|LOOP|"' is not a valid command.
What would be the best way to structure a call to a python script from within my macrofunction such that I can pass it parameters? I'm also not 100% sure that I structured the RUNPYFUNCTION MODULE command correctly. The double and single quotes that are used in the examples shown in the forum posts that were linked to earlier are confusing i.e. I don't always see a set of matching open and close quotations around the commands.
Thank you,
