Lab comparison

One account. 4 purpose-built workspaces.

DigiSim's labs share an account and plan framework, but they do not use a common simulation engine, editor, or project format. Select the model that matches the behavior under study.

What changes from lab to lab

Access and export controls can depend on the current plan. Beta and release status are shown explicitly.

What is shared

The platform layer is shared; the simulation models are specialized

One DigiSim account can cover all 4 labs, shared plan entitlements, cloud services, and a common course platform. Each editor then applies the representation, solver, instrumentation, persistence, sharing, and format rules appropriate to its domain.

Choose a workspace by its model and boundaries.

Review the release stage, persistence, sharing, and file workflow before opening a blank workspace or selecting guided content.
