Here's a response combining best practices for solver threads and GPU utilization in ANSYS Fluent:
Solver Threads:
The optimal number of solver threads for ANSYS Fluent depends on several factors:
- Available Hardware:
- Cores vs. Logical Processors: In modern CPUs, the number of cores and logical processors (threads) can be different due to hyperthreading. Generally, you can choose the number of logical processors. Hyperthreading allows each core to handle two threads simultaneously, potentially improving performance.
- RAM: As the number of threads increases, so does RAM usage. Ensure you have sufficient RAM to avoid bottlenecks.
