Multicore support in SOLIDWORKS 2026
1. modelling & sketching
o Basic operations (extrusion, rotation, etc.) usually only use one core.
o Some complex features (e.g. stiffeners, freeform surfaces) can benefit from multicore.
2. assemblies & large models
o The assembly calculation (e.g. movement analyses, collision check) sometimes uses several cores.
o Opening/saving large assemblies can be accelerated by multicore.
3. simulation (SOLIDWORKS Simulation)
o The FEM calculation (e.g. statics, thermics) is highly multi-core optimised (depending on the solver).
o Flow simulation also uses several cores efficiently.
4. rendering (PhotoView 360 & Visualize)
o Rendering is heavily CPU-dependent and uses all available cores.
o GPU acceleration (via NVIDIA CUDA/AMD) can also help.
5. drawing creation
o The creation of views and dimensions often runs single-threaded.
