Project Title: Implementing the Modified Inherent Strain Method (MISM) in CalculiX for Additive Manufacturing Simulation
Project Overview
I am working on an inherent strain simulation using CalculiX to predict distortion in metal 3D printing using the Modified Inherent Strain Method (MISM). The project involves layer-by-layer simulations where inherent strains are applied, and the resulting distortions are analyzed. However, the current implementation is producing inconsistent results, and I need expert assistance to refine the methodology and improve accuracy.
Current State of the Project
The following steps have already been completed:
✅ STL imported into the simulation workflow.
✅ Voxel mesh generated to represent the printed part.
✅ INP file generated, including element definitions and material properties.
✅ Layer-by-layer boundary conditions applied in the INP file.
✅ Result visualization implemented, showing the predicted distortion of the printed part.
Issues Faced
⚠️ Incorrect distortion distribution: The simulation results do not match expected experimental values. I am missing something in providing the correct boundary conditions for each layer or not accounting something.
⚠️ Inconsistency: Some cases produce accurate results, while others are significantly incorrect.
