Simulation

Cloud-Native Simulation

Onshape Simulation is a unique, proprietary, and cloud-native approach to finite element analysis (FEA), offering designers the ability to perform and share structural analysis from any web browser, anytime and anywhere.

Simulations are part of your Onshape Document, making it easy to leverage high-performance cloud computing for fast and interactive FEA – without leaving your design environment or requiring any specialized hardware.

Async Simulation

Offload compute-intensive structural analyses to the background, while you continue modeling uninterrupted queuing up to 50 concurrent jobs. These jobs execute from specific document versions using named positions or a version’s default position, ensuring all computed results are permanently stored in the Results and history table. This functionality automatically preserves an immutable, version-controlled record of design performance without tying up your active workspace.

Linear Static Analysis

Run linear static analyses and compare load cases quickly on full assemblies, not just parts. Fastened, revolute, slider, and other mates become simulation connections automatically. Apply forces, bearing loads, and constraints to whole parts or individual faces, then review stress, strain, and displacement without meshing or defeaturing.

Modal Analysis

Calculate natural frequencies and mode shapes for parts and assemblies to see how a design responds under vibration. Review each mode shape and energy to find where the structure is weakest, then change a part or configuration and the results refresh, so you can tune stiffness or adjust the distribution of mass before building and testing a prototype.

Rigid Parts

Treat fasteners, pins, and other part instances as rigid bodies. Rigid parts still move and carry load through the assembly, but their deformation isn't computed, so analyses solve faster and results focus on the parts you're studying.
