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

Following types of loading options are available in Midas NFX to facilitate efficient modeling.

Static Structural: Force, Gravity, Pressure, Displacement, Torque, Moment
Dynamic Structural: Velocity, Acceleration, Force
Thermal: Temperature, Heat Flux, Convection, Radiation, Heat Source
Fluid: Fluid Inlet, Fluid Outlet, Wall, Velocity, Pressure, Turbulence, Temperature, Heat Flux

The magnitude of these loads can also vary in space, time and frequency. This can be done by assigning spatial, time or frequency functions for the loads.


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 Analyst Mode of Midas NFX is a platform for the experienced FEA engineers, who have a deep understanding of its application of tools.

Unlike the designer mode, one can use different types of elements for modeling and also generate mesh manually. There are also tools to create and edit geometry, that can help the user tweak the geometry without the inconvenience of returning to the CAD platform.


Midas NFX offers a modern multiphysics work environment that enables engineers from different disciplines to analyze their design problems. The following analysis types are available in Midas NFX:

Structural Analysis: Linear Static, Modal, Linear Buckling, Transient Response (Direct & Modal), Frequency Response (Direct & Modal), Nonlinear Static, Nonlinear Quasi-Static, Random Analysis (Direct & Modal), Response Spectrum, Nonlinear Implicit Transient, Nonlinear Explicit Transient
Thermal Analysis: Nonlinear Heat Transfer (Steady & Transient), Linear Thermal Stress (Steady & Transient), Nonlinear Thermal Stress (Steady & Transient)
Computational Fluid Dynamics: Transient CFD, Steady State CFD

Post Processing

No position of the model can hide from the 짬 drag-and-drop 쨩 cutting plane. You can make an easy cut in seconds. Iso-surface directly tells you locations where stresses are higher than the allowable value.
