NextFEM Designer is a user friendly Finite Element Analysis program, which can be used alone or to be a pre- or post- processor for several widely used FEM programs (i.e. OOFEM, SAP2000, Midas GEN, OpenSees, ABAQUS/CalculiX, Zeus-NL, and others).

NextFEM Designer represents the future for FEA pre- and post-processing.
Read the list of its capabilities!

List of features:

  • general pre-processor capabilities: 3D and 2D views, customizable colours, accelerated rendering with DirectX technology;
  • modelling with the most common structural elements, such as beams, shells and solid elements;
  • importing input files from DXF drawings, OpenSees scripts, Midas GEN, SAP2000, ABAQUS, OOFEM, Zeus-NL;
  • importing results from SAP2000, OOFEM and OpenSees;
  • exporting models to SAP2000, ABAQUS, Midas GEN, OpenSees, OOFEM;
  • post-processing capabilities with deformed shapes with contour display, beam diagrams, stress and strain contour.

Documentation and help

Along with NextFEM Designer is provided an user manual which describes the main controls and procedures to get started with the program. Alongside with the manual, online support is available. It is possible to ask questions or give suggestions in the dedicated part of the NextFEM forum (http://www.nextfem.it/it/forums/).

NextFEM user interface

Display window looks like the figure below. It is possible to show the model (extruded or not), number of nodes or element, loads applied and general axis. On the bottom left corner number of nodes and elements of the model are shown.

NextFEM Designer can handle various type of models coming from other commercial software, such as OpenSees, SAP2000, OOFEM, ADAPTIC, Zeus-NL, Abaqus, CalculiX, Midas GEN. Thanks to its general abstraction classes, NextFEM Designer is the best way to convert a model from a program to another (eg. SAP2000 to OpenSees).

It can easily translate the geometry from one to another; in many cases (if the original software can export results), NextFEM Designer can be used also as a post-processor.

Customizable libraries

NextFEM Designer allows to use custom material and section libraries, adapting to the needs of an international audience.

Expand material library

The material library can be expanded by writing a CSV file (i.e. a text file using the semicolon separator), as in the following examples.

  • Steel

Name;Code;E [MPa];G [MPa];nu;fyk [MPa];ftk [MPa];Wd [kN/m^3];Md [kg/m^3]

S235;UNI EN 10025-2;210000;80769;0.3;235;360;78.6;801.2232416

S275;UNI EN 10025-2;210000;80769;0.3;275;430;78.6;801.2232416

  • Concrete

Name;Code;E [MPa];G [MPa];nu;fck [MPa];Wd [kN/m^3];Md [kg/m^3]

C8/10;NTC2008;25331;10555;0.2;8;25;254.841998

C12/15;NTC2008;27085;11285;0.2;12;25;254.841998

For other types of materials, all the columns are mandatory except for “fck”, “fyk” and “fck”.The extension of the file have to be *.nfm.

WARNING: units have to be written between square brackets

Expand section Library

The section library can be expanded by writing a CSV file (i.e. a text file using the semicolon separator) as follows:

Name;Code;h [mm];b [mm];tw [mm];tf [mm];r [mm];A [cm^2];Jy [cm4];Wey [cm^3];Wpy [cm^3];iy [cm];Avz [cm^2];Jz [cm^4];Wez [cm^3];Wpz [cm^3];iz [cm]

IPE A 80;UNI;78;46;3.3;4.2;5;6.375401837;64.37774091;16.50711305;18.97743881;3.177708713;3.070001837;6.852668856;2.979421242;4.692462888;1.036754887

The first four columns are mandatory. The extension of the file have to be *.nfs..
