It sounds like you’re describing a simulation involving hot strip rolling using the IMPETUS Afea Solver. This simulation involves a fully coupled thermo-mechanical process where you achieve a substantial 90% reduction in thickness without the need for remeshing. Here are some key points from your description:
- Simulation Software: IMPETUS Afea Solver is a finite element (FE) solver that specializes in explicit simulations, and it’s GPU-accelerated. This means that it utilizes the processing power of your nVidia Quadro P6000 GPU to perform simulations.
- Process Description: Hot strip rolling is a metalworking process where a metal slab is passed through a set of rolling stands to reduce its thickness and improve its mechanical properties. The simulation involves both thermal and mechanical effects.
- Thermo-Mechanical Coupling: The simulation is “fully coupled,” which indicates that it takes into account the interaction between the thermal and mechanical aspects of the rolling process. This is important because the material’s temperature changes due to the mechanical deformation, and these changes in temperature, in turn, affect the material’s mechanical behavior.
- Thickness Reduction: Achieving a 90% thickness reduction without remeshing implies that the simulation effectively captures the material’s deformation without needing to adjust the mesh (grid of nodes) during the process. This is significant because remeshing can be computationally expensive and complicated.
- Wall Clock Time: The simulation took 70 hours to complete. Wall clock time refers to the actual time that elapsed during the simulation, as opposed to the simulation time itself.
- Hardware: The simulation was run on a desktop computer equipped with an nVidia Quadro P6000 GPU. GPUs are well-suited for parallel processing tasks like finite element simulations due to their high processing power.
- Mesh and Time Steps: The simulation involved a slab with 217,000 nodes. A large number of time steps (2.4 million) were needed to complete the simulation, spanning 10 passes of the rolling process. This indicates the complexity and fine-grained nature of the simulation.
Overall, the information you’ve provided showcases the impressive capabilities of the IMPETUS Afea Solver and the computational resources required to perform a highly detailed and accurate simulation of a complex process like hot strip rolling. The ability to achieve a significant reduction in thickness without the need for remeshing suggests that the solver handles the mechanical deformation and material behavior changes effectively, contributing to the realism of the simulation results.
