Guidelines for contributing to abaqus_modules

To use your own abaqus-python functions with the czmtestkit, start by testing your function in the Abaqus/CAE Python Development Environment (PDE). Assume that abqPy_Func1 is your function based on abaqus-python scripting language with param_1, param_2 and param_3 as input parameters.

def abqPy_Func1(param_1, param_2, param_3):
    # The function code to be tested goes below

Ensure the command is exectable without errors in the PDE, using the following command after assigning values of corresponding data types:

abqPy_Func1(param_1=value_param1, param_2=value_param2, param_3=value_param3)

Then, convert the function to make it compatible with czmtestkit with the following changes.

def abqPy_Func1(dict): # Change input parameter
    for k in dict.keys(): exec("{0} = dict[\'{0}\']".format(k)) # New line to be added to the script
    # Rest of the tested function code goes below

Now you can pass a dictionary of variables to abqPy_Func1 with keys param_1, param_2 and param_3 and values of corresponding data types. For example:

In_dict_Func1 = {
    'param_1': value_param1
    'param_2': value_param2
    'param_3': value_param3
}
abqPy_Func1(In_dict_Func1)

After testing the funciton in the PDE, create a moduleName.py file in the abaqus_modules subdirectory and copy the converted function code (def abqPy_Func1(dict):...) to this file. Further, import the funciton to the czmtestkit.abaqus_modules module by appending the following line to the abaqus_modules\__init__.py file.

from moduleName.py import abqPy_Func1

    $ Local czmtestkit repository
    ├── ...
    ├── czmtestkit
    |   ├── abaqus_modules
m#  |   |   ├── __init__.py
    |   |   |   └── ...
+#  |   |   |       from moduleName import abqPy_Func1
+#  |   |   ├── moduleName.py
    |   |   └── ...
    |   ├── py_modules
    |   └── __init__.py
    ├── ...
    └── setup.py

Make sure the names moduleName and abqPy_Func1 are unique and have not already been used. Further, if you have more than one function in moduleName.py file, use the following command to import all the funcitons at once.

from moduleName.py import *

Finally, reinstall the czmtestkit locally (see ) and test your module with czmtestkit.py_modules.abqFun().

# Create dictionary
In_dict_Func1 = {
    'param_1': value_param1
    'param_2': value_param2
    'param_3': value_param3
}

# Write data to a .json file
import json
filePath = 'dataIn.json'
with open(filePath, 'a') as file:
    json.dump(In_dict_Func1, file)
    file.write("\\n")

# Execute the abaqus-python script with czmtestkit
import os
czmtestkit.py_modules.abqFun(filePath, 'czmtestkit.abaqus_modules.abqPy_Func1',os.getcwd())

Now that you verified your script with the czmtestkit, go ahead and send us a pull request to share your code with the world. While this step is optional, we highly encourage you to do this.
