Stress Output Assistance

Submitted by davis850 on Tue, 01/17/2023 - 19:09

Hello, experienced LIGGGHTS users,

My name is Jake, and I am relatively new to the LIGGGHTS software. I am currently working on a model that involves simulated soil particles being impacted by other particles to create stress on the soil. So far, the model is running smoothly, and I have specified a compute command that specifies soil stress. In Paraview, I am able to see the soil stress (c_regionStress[1], c_regionStress[2], c_regionStress[3], etc.) but I am having trouble obtaining a stress output for my soil. The log file that I've generated only shows the step, number of atoms, kinetic energy, and volume, but I need to have additional columns showing c_regionStress[1], c_regionStress[2], etc.

My main objective here is to generate a log output file that contains soil stress values, so that eventually, I can modify the material properties of my soil to see how the soil stress values change depending on certain physical characteristics, such as friction, energy density, and so on. Unfortunately, Paraview alone isn't enough of a reference when it comes to finding specific soil stress values in specific locations.

Any help here would be appreciated. I've attached my working text file for reference.

Very respectfully,
Jake
