I’m using Abaqus to simulate a pillar with brittle material subjected to nanoindentation, with the goal of determining the stress required for an unstable crack. I’m creating the model with a Matlab file and running the simulations with a job.inp file. I can choose the mesh and radius of the pillar in Matlab, but I’m stumped as to why, with the same job parameters and mesh, I get different load trends for different pillar’s radius.
Thank you for any suggestions.

Hello,
I think you get a different trend for the load because your model is nonlinear, so you shouldn’t necessarily obtain the trend you expect, and it could be different. Moreover, why did you use Matlab for meshing anyway? With the ABAQUS itself, you could more easily mesh the model and optimize it, refer to this link: https://caeassistant.com/product/python-scripting-in-abaqus-part1/
If you really need to use Matlab, I think this link might help you as well: https://caeassistant.com/product/linking-abaqus-matlab-for-beso-topology-optimization/
