CAD/CAE Interfaces

CAD geometry can be directly imported into midas NFX from all the major CAD programs. The data translation is fluent, efficient and with minimum loss.

Supported formats include: CATIA, Inventor, Pro-E/Creo, Solidwords, Solid Edge, Parasolid, Unigraphics, ACIS, STEP, IGES, etc.

Geometry Modeling

Midas NFX offers various features and options to create your own geometry from scratch. The tools can be used for creating line, surface and solid geometries.

In addition, tools such as Boolean operations, mid-plane extraction, CFD volume creation etc, help you edit your geometry in a very convenient manner.

There are also tools to help the engineers check the quality of geometry, locate discontinuous curves, duplicate curves & surfaces, etc.


Manual mesh generation provides to the user the freedom to generate a mesh from scratch, eliminating the need of preparing parametric geometric models.

Options include extrude, sweep, revolve, project, fill and offset 2D mesh profiles into 3D sets.

The user can also divide elements, modify element parameters, or check the quality of the mesh generated.

Loads & Constraints

To emulate the physical conditions of a model effectively, it is essential that the constraints are properly assigned to the FE model.

Some of the default constraints, such as fixed constraint, pinned (hinged) constraint and rotational constraint can be automatically applied in Midas NFX. Individual degrees of freedom (translational & rotational) can also be constrained.

In addition, for models with symmetric geometry and loading conditions, symmetric constraints can be used.


Midas NFX provides a database of more than 1000 linear material models, which helps to simulate behavior of almost any kind of material. 

Based on the caracteristics, materials can be further divided in to linear, elasto plastic, hyper elastic, nonlinear elastic and temperature dependent materials.

NFX Working Modes

The Designer Mode of Midas NFX is a single answer to all engineers who aspire to take that intellectual leap from being a CAD designer to an FEA analyst.

Powerful meshing algorithms complimented by high-performance Midas solvers, makes Midas NFX Designer mode the ultimate tool for novice and amateur engineers.
Options such as automatic model simplification, auto-update and analysis wizard make FEA less cumbersome for even the most advanced FEA users.


Parallel-processing: Midas NFX allows you to utilize the computing power of your hardware to its full potential by supporting multiple cores of your computer at no extra cost.

GPU-enabled computing: Use your computer graphical processing unit as a means to boost your computing power. Currently supported hardware included.

Post Processing

The visual representation of results is one of the biggest strengths of Midas NFX. Powerful post-processing tools enable easy visualization as well as extraction of results. Some of these tools have been listed below:

  • Contour Maps
  • Iso-Surfaces
  • Clipping Planes
  • Probe Tool
  • Tables
  • Graphs
