I recently discovered this useful tool. For the preliminary case, I was trying to implement a simple linear elastic uniaxial extension optimization problem using ABAQUS/Explicit. The aim is to estimate the optimum material properties. I have written the code and I need to compare the displacement field with that of experimental data. The code, however, is converging after only three iterations and showing the initial estimate of material properties to be the optimum values. However, based on the experimental data, the optimum values should be E = 300 GPa and Poisson's ratio = 0.3. I'm attaching the complete code for reference. I would be grateful if someone could look into the matter. Link for files: https://drive.google.com/drive/folders/1oQJ0-pfUHXnaFDtiQPEJjpBGa2Cdl1GQ?usp=sharing Regards Abhilash

I want to extract the angle of ply or layer of laminate orientation and it's related stress respectively, to optimize the stacking sequence of ply angles. please help me to solve this problem. with best regards

Hello to everyone, I am a beginner using this tool and when I was trying to understand the example 3 a doubt came up: It is not clear for me what it is done in the step and why: "Shift in element numbering (the first element number of the Abaqus model is eleshift+1)" specifically, about eleshift+1. Could you help me out to better understand this step? Thank you in advance.
