SimSolid Software | Meshless Structural Simulation for CAD Assemblies

SimSolid lets you run structural simulation directly on CAD assemblies so you can evaluate stress and displacement without the traditional meshing workflow. It’s built for rapid design iteration, where geometry changes often and you need answers fast, so engineering teams can move from “CAD complete” to “study complete” with less model-prep overhead while still maintaining an engineering-grade workflow.

SimSolid is designed to handle complex, large assemblies and the real conditions that come with them—like rough contact surfaces, gaps, and overlapping geometry—so you can analyze the structure you actually have instead of spending cycles forcing the model into an “analysis-perfect” state. This is especially valuable when you need practical insight across many parts, interfaces, and load paths without slowing down your development pace.

SimSolid supports a broad set of analysis types used in day-to-day structural engineering, so teams can validate stiffness, strength, vibration behavior, thermal effects, and durability trends within one fast workflow. That coverage makes it easier to run meaningful what-if comparisons across concepts and design revisions and keep simulation active earlier in the design process, not only at the final validation stage.

SimSolid includes robust options for defining how parts interact so your assembly setup can represent realistic load transfer through interfaces, fasteners, and joints. With practical connection modeling and contact behavior, you can focus on the assumptions that matter—how the assembly is held together and where forces flow—while keeping setup efficient and consistent across iterations as designs evolve.

SimSolid supports the kind of load and constraint definitions engineers rely on to represent real operating conditions, enabling repeatable studies across design alternatives. This helps you build a consistent workflow for applying boundary conditions, comparing scenarios, and evaluating sensitivity to assumptions—so results can drive decisions instead of becoming a one-off exercise that’s hard to replicate.

SimSolid is built to help teams interpret outcomes quickly and communicate structural behavior clearly across the organization, supporting faster design decisions and iteration cycles. By making it easy to review results, compare scenarios, and understand where structural demand concentrates in an assembly, teams can shorten the loop between simulation insight and the next design change—especially when paired with expert guidance to validate assumptions and improve study setup.
