Successfully Running **ck_version** and **sycl_version** of Soil Mechanics

[ShuangLi-1]

Based on your previous guidance, I have re-debugged and corrected the ck_version and sycl_version of the soil mechanics module.

The issue was caused by a division by zero in the constitutive equation calculations, which I have now fixed. Thanks for your guidance.

Additionally, I have created two cases:

• 2d_column_collapse_ck
• 2d_column_collapse_sycl

On my computer, these cases can run successfully in Release mode, and the GPU is being utilized correctly. Please check them at your convenience.

Supplementary Notes

1. For matrix transformation purposes, I copied Pull Request inlined vector up and degrade #703 (inline vector up and degrade) into my current version.
2. This is a new account created using my Google email. I will use this account moving forward.

@Xiangyu-Hu
Thank you for your prompt response and guidance.
I have updated my code based on the latest master branch, made the necessary adjustments, and tested it. The corrected version avoids any inconsistencies with the current version and successfully runs both the CK and SYCL versions of the soil mechanics.
The changes have been updated in the pull request.

Thank you again for your support during the holiday season, and I wish you a Merry Christmas!

@ShuangLi-1 Linux (g++) build is quite strict, and requires even no warning message. You can try to build using g++ locally first.

Ok, I will try it. Thanks

I have modified the code to avoid the issue where the initialization order of variables differs from the definition order, as mentioned in the error message in this PR.

Locally, I can successfully compile and run 2d_column_collapse_ck with g++ and the -Werror=reorder flag, as shown in the screenshot.

Perhaps further testing can be performed.

You need have a regression test like

SPHinXsys/tests/2d_examples/test_2d_column_collapse/column_collapse.cpp

Lines 223 to 230 in a2df28d

	if (sph_system.GenerateRegressionData())
	{
	write_mechanical_energy.generateDataBase(1.0e-3);
	}
	else if (sph_system.RestartStep() == 0)
	{
	write_mechanical_energy.testResult();
	}

I have added it and pushed it. But I don't know how to test it on my own computer.

[Xiangyu-Hu]

You need to copy the data files to here from the CPU version of this case.

tests/2d_examples/test_2d_column_collapse/regression_test_tool

So that the regression test can be carried out automatically when you run the case.
