When performing contact analysis in RecurDyn, using SMP (Symmetric Multi-Processing) can significantly reduce analysis time. SMP activation allows the automatic utilization of multiple cores, and key contact algorithms like Geo Surface Contact are optimized for multi-core processing, reducing analysis time by 30-50%.
What is SMP?
SMP is a technology that processes tasks in parallel by sharing multiple CPU cores under a single operating system (OS), enabling rapid resolution of large-scale systems of equations such as contact and collision calculations. Starting with RecurDyn 2025, SMP supports up to 8 cores by default, and an additional SMP license is required for more than 8 cores.
Accelerating Contact Analysis with SMP
- Automatic Multi-Core Utilization: If you set the 'Number of Core' option to Auto, the system automatically detects and utilizes up to 8 available CPU cores for parallel processing starting from RecurDyn 2025.
- Over 50% Time Savings: Applying SMP to Geo Surface Contact results in a reduction of analysis time by 40-50%, depending on model complexity.
- Expanded Support for Various Contact Types: SMP (Shared Memory Parallel) is applied to major contact types such as Geo Surface, Geo Sphere, Geo Cylinder, Geo Curve (2D/3D), and Geo Circle, enabling a 30-50% improvement in analysis speed.
Analysis Speed Comparison
Setting Up SMP in RecurDyn
- Go to the Home tab → Settings group → Click the Simulation button.
- Set the 'Number of Core' option to Auto, and the system automatically detects and utilizes up to 8 cores. You can also manually enter the desired number of cores.
- To use more than 8 cores, an additional SMP license is required .
Practical Tips for Application
- Check CPU usage before analysis and minimize background processes if necessary.
- Understand the characteristics and complexity of each contact model, and actively use Geo Contact types that support SMP for better performance .
- If analysis time is longer than expected, even with the Auto setting, try manually adjusting the number of cores or consider expanding the SMP license.
Using SMP in RecurDyn can significantly reduce the time required for contact analysis. The advantages of multi-core parallel processing are more pronounced as the model's contact complexity increases, so it's recommended to review analysis environment settings and license configurations in advance to establish an optimal analysis workflow.
