Siemens Simcenter FEMAP 2021.2.0 with NX Nastran

FEMAP 2021.2 New Features - Date: 16 Juny 2021

Faceted Geometry Support and Body Mesher Technology
With this release, Femap adds support for convergent modeling, allowing users to import/export, edit, and mesh geometry composed of triangular facets alongside more traditional Parasolid boundary (B-Rep) geometry. The ability to mesh faceted geometry in Femap is possible thanks to the new Body Mesher Technology, which leverages remeshing capabilities from STAR-CCM+ to generate high-quality meshes on complex surfaces that would be challenging and tedious to mesh with traditional workflows.

Mesh quality is the primary goal of Body Meshing, and geometry simplification and idealization are not required. Nodes and elements are associated only with points, curves, and surfaces selected by the user or with existing boundary conditions, so it is important to create loads, constraints, and regions in advance.

In addition to automatic geometry cleanup, the Body Mesher Technology allows Femap to mesh STL facets of topology-optimized shapes. It also enables the new Mesh on Mesh command, which can be used to remesh selected elements to improve mesh quality and/or modify mesh density.

Mesh Control Explorer Enhancements
The Mesh Control Explorer can now be used to show edges that are adjacent to surfaces and surfaces that pierce other surfaces without having imprinted curves at the intersection locations. Once imprints are created, the Mesh Control Explorer offers the ability to create a fully connected mesh at all intersections without the need to combine surfaces with a NonManifold Add command.

JT Visualization File Export
Femap 2021.2 gives users new export options for JT visualization files, which can be used in the Teamcenter for Simulation environment or other JT collaboration tools to visualize model data and review results without the need to open an instance of Femap.

Solver Support
Beginning with Femap 2021.2, users can specify subcases for transient, frequency response, and nonlinear transient response analyses. This capability can be used to specify frequency, time step, or nonlinear parameters in different dynamic subcases or account for stress stiffening and optionally impose contact conditions using a static subcase.

This release also adds the ability to create and edit Nastran CBUSH1D elements, which are 1D spring/damper elements that support large displacements for nonlinear analysis.

Support was also extended for reading and writing the MPLAS card in Simcenter Nastran SOL 401/402 and for reading pyramid element results from MSC Nastran's .f06 file. LS-Dyna support was added for element formulations EQ18 and EQ-18 for solid elements as well as element formulation EQ16 for shell elements.



Simcenter Femap softwareis a standalone finite element modeling (FEM) pre- and postprocessor for engineering simulation and analysis. The software is computer-aided design (CAD) independent and can import geometry from all major CAD platforms. It supports most CAD data formats. Simcenter Femap also works in combination with a wide variety of FEA solvers, including Simcenter Nastran® software.

Simcenter Femap, which is part of the Xcelerator portfolio, the comprehensive and integrated portfolio of software and services from Siemens Digital Industries Software, is now being released on a biannual schedule in the spring and the fall, which began with version 2019.1 and continues with version 2021.2. The software is now referred to as Simcenter Femap to reflect that it is a part of the Simcenter portfolio of Siemens computer-aided engineering (CAE) products. For the same reason, NX Nastran software is now Simcenter Nastran software.

Siemens PLM Software.a business unit of the Siemens Digital Factory Division, is a leading global provider of software solutions to drive the digital transformation of industry, creating new opportunities for manufacturers to realize innovation. With headquarters in Plano, Texas, and over 140,000 customers worldwide, Siemens PLM Software works with companies of all sizes to transform the way ideas come to life, the way products are realized, and the way products and assets in operation are used and understood.

Welcome to FEMAP! This document will help you to setup your computer so that you can immediately begin to explore the many capabilities of FEMAP.

This document contains information specific to getting started on a PC, which includes 64-bit versions for Windows 7, Win-dows 8, Windows 8.1, and Windows 10.

The FEMAP installer contains only the 64-bit version of FEMAP, as a 32-bit version is no longer available.

Hardware/Software Requirements
There are no special hardware/software requirements for FEMAP beyond those imposed by the Windows operating systems. There are many types of hardware that will allow you to use FEMAP. Proper choice of hardware, however, can often make the difference between frustration and productivity. Here are a few suggestions:
- Memory, RAM
- Memory, (Hard Disk)
- Graphics Boards
-Abaqus ODB Requirements

Memory, RAM
You will need at least 128 Mbytes of RAM to run FEMAP and the Parasolid solid modeling engine, which is the default. Obviously, the more amount of RAM the better. Adding RAM can be one of the most cost effective means of increasing per-formance.If using the "Standard" geometry Engine in FEMAP, you can actually run with as little as 32 Mbytes of RAM. This is not a recommended configuration.

Memory, (Hard Disk)
Required hard disk space is very difficult to estimate, but in general you will never have enough. Analysis results will be the main driver of any disk space requirement. Models are typically relatively small. A model with 1000 nodes and 1000 ele-ments would typically be less than 1 Mbyte in size. Output from an analysis of that model, however, could be 5 Mbytes, 10 Mbytes or even larger, depending on the output you request. To estimate total disk space, you need to first estimate how many models you will have on-line simultaneously, the approximate size of those models, and the type of output you will request. It is recommend to have as much disk space as budget will allow, as each version of FEMAP can support larger and larger models, which in turn create larger and larger amounts of output.

Graphics Boards
While, standard graphics adapters may work very well with FEMAP, having a specialized board with support for OpenGL will provide increased graphical performance when dynamically rotating large, complex models. They also usually provide higher resolution and more colors, which make graphics easier to see and more realistic. Also, in order to use the "Perfor-mance Graphics" option, a graphics card which supports OpenGL 4.2 is required.
