E502 & E503

This add-on provides a dynamic response addition to Simcenter Femap with Simcenter Nastran: Basic. Dynamic Response determines the response of models that are subjected to loads that vary with time or frequency. Dynamic Response includes:

  • A comprehensive range of response simulation capabilities
  • Normal modes and complex eigenanalysis
  • Frequency & transient response analysis
  • Acoustic analysis
  • Response and shock spectrum analysis
  • Random vibration analysis
  • It can be effectively coupled with other analysis types such as super elements and design sensitivity and optimization
  • Covered Simcenter Nastran Solution sequences include: 107, 108, 109, 110, 111, 112, 118, and 187

E520 & E521

Simcenter Femap with Simcenter Nastran: Advanced Dynamics brings together more advanced dynamics add-on tools to the Simcenter Nastran Desktop solver. As such, it builds upon the Simcenter Nastran solution and is ideal for customers who have a need for more advanced dynamics solutions. Over and above Simcenter Nastran Basic, Simcenter Nastran Advanced Dynamics is able to provide state-of-the-art solutions for more advanced engineering simulation. It provides support for:

  • Dynamic analysis
  • Aero-Elasticity
  • DMAP
  • Super Elements
  • The bundle also provides support for distributed parallel processing (DMP)
  • Covered Simcenter Nastran Solution sequences include: 107, 108, 109, 110, 111, 112, 118, 144, 145, 146, and 187

E401 & E402

Predict the behavior of parts or assemblies with nonlinear contact, nonlinear material, or large deformations

The Nastran Multi-step Nonlinear software solution enables you to analyze models with nonlinearity from contacting parts, material property nonlinearities, and/or geometric nonlinearities (that is, large deformations and large strains). This solution is an add-on module of Simcenter Nastran – Basic in either enterprise or desktop versions. The Multistep Nonlinear license provides access to both the SOL 401 Multistep Nonlinear solver and the SOL 402 Multistep Nonlinear Kinematic solver. Both use nonlinear implicit methods based on similar formulations. SOL 401 is implemented in the standard Simcenter Nastran architecture and leverages the same code base as other Simcenter Nastran solutions. SOL 402 is an integration of the well-known and highly regarded Simcenter Samtech Samcef™ solver into Simcenter Nastran. Either solver can be used to solve a large class of nonlinear solutions and give very similar results. Other classes of nonlinear solutions may be better solved using one or the other. Users can refer to the Simcenter Nastran documentation to see which solver may best support their applications or consult with the Siemens support organization.


  • Reduce design risk by using simulation to save time and cost compared to physical build-and-break test cycles
  • Accelerate your innovation through rapid iteration and numerous “what-if” studies
  • Use the same models already built and analyzed linearly with Simcenter Nastran – Basic
  • Improve confidence in final designs by virtually investigating your product’s performance under all possible operating conditions
  • Obtain more accurate solution results than linear analysis when standard linear assumptions are not valid

E307 & E308

The Simcenter Femap Advanced Thermal Solver adds a number of more advanced thermal modeling and simulation capabilities to the Femap Thermal Solver package including 1D fluid network modeling and free and forced convection. An extensive suite of thermal modeling tools are provided to allow users to define more advanced and sophisticated thermal simulations, such as:

  • Radiation and spacecraft modeling
  • Solar and orbital heating
  • Orbit modeling and display
  • Ray tracing capabilities
  • Articulating structures

These extensive modeling tools are also complemented by a number of more advanced solver features such as:

  • Custom user subroutines
  • Model simplification
  • Sub-structuring
  • Interfaces to industry thermal codes

E508 & E509

Provides specific optimization support for any versions of Simcenter Femap with Simcenter Nastran. With this module, you can improve upon existing designs through the manipulation of element properties such as plate thicknesses and beam sections. The design can therefore be optimized to minimize weight for example, while maintaining specific responses such as displacements or stresses.

Optimization may be applied to a broad range of Simcenter Nastran analysis types, such as:

  • Linear statics
  • Normal modes
  • Buckling analyses

In addition, it also includes a broad range of optimization capabilities that can be used with the more advanced Simcenter Nastran capabilities such as dynamic response.

E522 & E523

This add-on capability to desktop licenses removes a core Simcenter Nastran limitation: the Nastran input file for solution must be written out by Simcenter Femap and cannot be edited by the user from the OS.

With this add-on users are, in most cases but not all, able to edit the input files from the OS. The Node Locked version of the Desktop Extension still has the limitation that it must be run on the same computer as Femap.
