| - | To add a new test, the user should: | + | ==== Creating your test ==== |
| - | * Add the new test to "http://www.lagamine.uliege.be/dokuwiki/doku.php/battery/listtests" | + | |
| - | * Modify the file **Test_battery.txt**: add the name of the new test | + | In order to ensure that your developments in the Lagamine code will keep functioning properly, it is highly recommanded that you add one or several tests specific to the law(s) or element(s) you use and develop. \\ \\ |
| - | * Add the folder of the new test (to the test battery directory) containing: | + | To test a material law or an element, you should design a **simple test**, using only 1 element when possible. Preferably, your test should **not take more than a few seconds** to run. If you need to test something more complex, you can also create a "Big" test. However, the total number of Big tests should be limited to avoid excessive computational times for the whole test battery. \\ |
| + | //For instance, to test the visco-plastic 'CHAB' law, I created a test using a single element submitted to 2 cycles of alternated tension and compression (see [[battery:listtests:test7|CHAB_SC_TMF]]).// \\ | ||
| + | |||
| + | Once you have designed your test and created the necessary simulation files, you must identify the important variables that indicate whether your law/element is behaving as it should. \\ | ||
| + | //For the 'CHAB' law, I will check the values of the stress tensor, the thermal strain, the plastic strain along the loading direction, and the damage variables. These values can be obtained via the [[appendices:a9|*.ipe result file]].// \\ \\ **Be sure to print out the values you want to check at the time step(s) you see fit**. \\ To define the time steps at which you want a printing, you can use [[lagamex:auto#rd_line_14i5_-_strategy_control_data|ILSAV = 1 or 2]] in the ex.dat file. \\ Check [[appendices:a1|Appendix 1: Printing options]] and [[appendices:a9|Appendix 9: Printing files]] for more info about printing files. | ||
| + | |||
| + | ==== Comparator code ==== | ||
| + | After you have created your test and identified the variables that need to be checked, you need to write the comparator code. \\ \\ This code should be written in a Python script. If Python is not already installed on your computer, you can download it from the official Python website: [[https://www.python.org/downloads/|https://www.python.org/downloads/]] \\ Several editors exist to facilitate coding and debugging with Python. You can use [[https://www.spyder-ide.org/|Spyder]] or [[https://code.visualstudio.com/|Visual Studio Code]] for instance.\\ | ||
| + | |||
| + | For the comparator code, it is recommanded to use one of the existing comparators as an example. You can search in the Dokuwiki tests that use the same type of result files as you to find a code similar to what you should write. \\ | ||
| + | |||
| + | ==== Adding your test to the battery ==== | ||
| + | |||
| + | To add a new test to the battery, you should: | ||
| + | * Add the new test to "http://www.lagamine.uliege.be/dokuwiki/doku.php/battery/listtests" | ||
| + | * Modify the file **Test_battery.txt** on Obelix: add the name of the new test | ||
| + | * Add the folder containing your test to the test battery directory. This folder should contain: | ||
| * The files of simulation (with the same name as the test) | * The files of simulation (with the same name as the test) | ||
| * The reference simulation folder (with the same name as the test + "_ref") | * The reference simulation folder (with the same name as the test + "_ref") | ||
| - | * The comparator python script (with the same name as the test): take an existing script and adapt it to the new test | + | * The comparator python script (with the same name as the test) |
