Transitioning from SpaceClaim to Ansys Discovery: What It Means for Designers and Engineers

For many engineers, Ansys SpaceClaim has been a dependable part of the simulation toolset for years. Its direct modelling philosophy and fast geometry preparation made it particularly popular for simulation setup and design clean‑up.

Now, with SpaceClaim entering maintenance mode and scheduled for discontinuation, attention is turning to Ansys Discovery. While this raises practical questions about tools and workflows, it also signals a broader shift in how simulation is meant to support design.

This blog explains why the move from SpaceClaim to Ansys Discovery is happening, what changes in practice, and how simulation‑driven design reshapes the engineering process.

Why Ansys Is Moving Away from SpaceClaim

SpaceClaim isn’t being phased out because it failed. Quite the opposite. Its strengths form the foundation of Discovery.

What has changed is the role simulation is expected to play. Traditional design processes treat simulation as a late‑stage validation step, limiting its influence on the final design. As products become more complex and development cycles tighter, that approach increasingly leads to:

• Late design changes with high cost
• Conservative decisions based on experience rather than physics
• Missed opportunities for optimization

Ansys Discovery was created to address this, enabling engineers to explore ideas earlier and iterate faster, with physics guiding decisions from the start.

From Linear Process to Simulation‑Driven Design

Many engineering processes still follow a sequential pattern: design first, analyse later. While structured and familiar, this linear workflow often restricts creativity.

Simulation‑driven design flips that model. Instead of validating decisions after they’re made, engineers use simulation continuously to inform design choices. Geometry and physics evolve together.

This approach enables:

• Faster design exploration
• More iterations with less effort
• Earlier insight into potential failure modes
• Improved confidence in final concepts

Ansys Discovery is designed specifically to support this way of working.

Ansys Discovery vs SpaceClaim: What Stays the Same and What’s New

What Carries Over from SpaceClaim

Existing SpaceClaim users will find much of Discovery familiar:

• Direct modeling tools remain central
• Geometry repair and preparation are still fast and intuitive
• SpaceClaim files open directly in Discovery without data loss
• Parameters, materials, colours, layers and annotations are preserved

For most teams, no special conversion is required to continue working with existing models.

What Ansys Discovery Adds

Where Discovery moves beyond SpaceClaim is in integrating simulation directly into the modeling environment.

Key additions include:

• Built‑in simulation, available alongside geometry editing
• GPU‑accelerated Explore mode for rapid design feedback
• Refine mode for higher‑fidelity analysis using traditional solvers
• Live simulation updates as geometry changes

This allows engineers to test ideas, understand sensitivities and compare alternatives in real time, not days later.

Using Simulation Earlier in the Design Process

One of Discovery’s biggest strengths is how naturally it supports early‑stage simulation. As design changes are made, results such as stress, deformation or safety factor can update automatically.

This dramatically reduces the barrier to using simulation during concept development and encourages experimentation, making it easier to identify stronger and more efficient solutions early on.

CAD, Discovery and Workbench: A More Connected Workflow

Ansys Discovery strengthens integration across the wider toolchain:

• Associative CAD connections allow native CAD updates to flow directly into Discovery
• Seamless transfer into Ansys Workbench preserves geometry changes, loads and boundary conditions
• Design exploration in Discovery can feed directly into detailed validation

The result is less rework and a smoother transition from concept to final analysis.

Documentation and Design Communication in Discovery

Instead of traditional drawings, Discovery introduces an ‘Engineering Notebook’. This supports:

• Design views
• Annotations
• Notes explaining engineering decisions

While not intended to replace manufacturing drawings, it works well for capturing and communicating design intent during early and mid‑stage development.

Will Ansys Discovery Fully Replace SpaceClaim?

For most use cases, yes.

The majority of SpaceClaim functionality already exists within Discovery, with new capabilities continually added. Some features are implemented differently, reflecting a stronger focus on simulation and exploration rather than pure geometry management.

Importantly, ongoing development effort is concentrated on Discovery, making it the platform best aligned with future Ansys workflows.

Making the Transition with Confidence

Switching tools is rarely comfortable, especially when established processes are involved. However, the transition from SpaceClaim to Ansys Discovery isn’t just a technical change. It represents a move toward using simulation as a design driver, not just a checking tool.

For engineering teams ready to embrace that shift, Discovery opens the door to better decisions, faster iteration and more optimal designs, all while building on the foundations SpaceClaim users already know.
