Features Supported for Import from Abaqus/CFD

When you import an Abaqus/CFD simulation from an input file (.inp), the import process replicates the nodes and elements from the Abaqus data in the 3DEXPERIENCE platform. The import process also replicates a subset of the other features present in the data, such as physics settings, boundary conditions, and output requests.

Some Abaqus/CFD components are supported by the import process but do not appear in the user interface. The contributions of these components are included when you perform your analysis, but you cannot change them directly in the app.

This page discusses:

Step

Abaqus Usage 3DEXPERIENCE Usage
If your Abaqus/CFD input file includes multiple steps, 3DEXPERIENCE imports only the first step.
*CFD, INCOMPRESSIBLE NAVIER STOKES, STEADY STATE Steady-state flow step with the following parameters from the Abaqus/CFD step:
  • Error threshold
  • Total iterations
  • Solver controls: enable the same individual solvers (such as momentum equation, turbulence, and pressure) and specify the same parameters for each one, including under-relaxation parameters
*CFD, INCOMPRESSIBLE NAVIER STOKES Transient flow step with the following parameters from the Abaqus/CFD step:
  • Total time
  • Divergence tolerance
  • Maximum fixed point iterations
  • Error threshold
  • Incrementation schema (either FIXED CFL or fixed Time increment supported) with accompanying data (max cfl, or fixed time increment for example, but all parameters are supported for both incrementation schemas)
  • Solver controls: enable the same individual solvers (such as momentum equation, turbulence, and pressure) and specify the same parameters for each one, including under-relaxation parameters
