How to install Abaqus
Abaqus 2017-2019 on Windows
- The retrieved .TAR files need to be extracted in a way that allows their contents to mix together. We recommend installing the free 7-Zip program and using the “Extract here” option. After extraction you should have a subdirectory named “AM_SIM_Abaqus_Extend.AllOS” containing all the installation software.
The detailed Installation Guide will be found at this location amongst the extracted files: AM_SIM_Abaqus_Extend.AllOS\1\SimuliaInstallationGuide.pdf
- We do not recommend installing the local documentation with the latest versions of Abaqus. The local search does not work well and the files require a lot of disk space. The online documentation is much better and is available here: http://help.3ds.com
- The “Suite Installer” will step you through the separate installation programs for each of the optional components (Abaqus license, solver, CAE, Tosca, Isight, etc). Start the Suite Installer found at this location amongst the extracted files: AM_SIM_Abaqus_Extend.AllOS\1\setup.exe
Abaqus 2016 on Windows
Note: If you need help installing a different version of Abaqus or help installing on a different operating system, the instructions are different than those below.
The contents of the tar files need to be extracted in a way that allows them their contents to overlap directories. One way to do this is by using 7-zip: select all files, right click, 7-zip “extract here”. You should find a subdirectory named “AM_SIM_Abaqus_Extend.AllOS” with the installation software within.
You will find the license server setup buried within that subdirectory (and many more) at this location: AM_SIM_Abaqus_Extend.AllOS\1\SIMULIA_FLEXNet\Windows64\1\setup.exe
The documentation will need to be installed next, either on a central computer or on each client’s workstation. Once you extract the “2016.AM_DOC_SIM_EstPrd.AllOS.tar” file you will find the documentation server setup program here: AM_DOC_SIM_EstPrd.AllOS\1\DOC_SIMULIA_Abaqus_fe-safe\1\Abaqus_2016\setup.exe
By the way, the Installation and Licensing Guide, which explains this whole process in detail is located here: AM_DOC_SIM_EstPrd.AllOS\1\DOC_SIMULIA_Abaqus_fe-safe\1\Abaqus_2016\INSTALL_LIC.pdf
Once the license and documentation are set up then you may begin installing software on the client machine(s). The client programs are currently broken into many separate installers that should be run in this order: AM_SIM_Abaqus_Extend.AllOS\1\3DEXPERIENCE_AbaqusSolver\Windows64\1\setup.exe AM_SIM_Abaqus_Extend.AllOS\1\CAA_3DEXPERIENCE_AbaqusSolver\Windows64\1\setup.exe AM_SIM_Abaqus_Extend.AllOS\1\SIMULIA_Abaqus_CAE\Windows64\1\setup.exe

How to Read Abaqus Release Notes
Abaqus release notes are substantial documents full of useful information. They are the place to learn about new features, new conveniences, and new performance upgrades. These release notes are well organized so you can easily navigate to what is relevant to you, so be sure to give it a look!
Here’s how you get to them:
1. Visit help.3ds.com and log in.
2. Pick a SIMULIA year from the pulldown menu.
3. Click for SIMULIA/Abaqus products.
4. Expand Abaqus.
5. Click Release Notes.

Tips & Hints
General Contact in Abaqus / Standard
General contact in Abaqus/Standard uses the surface-to-surface finite-sliding contact formulation. This formulation can also be used for contact pairs, but it is not the default. The unsymmetric solver (*step, unsymm=yes) is highly recommended to speed convergence for surface-to-surface contact or node-to-surface contact with highly curved master surfaces.
Debug Numerical Singularities
Use a Frequency (normal modes) analysis to verify that a model is fully constrained. All materials will need to have a density assigned for this analysis procedure. Any results with a frequency near zero are indications of an under-constrained model which will show up as NUMERICAL SINGULARITY convergence difficulties in Abaqus/Standard. Animate these modes to visualize the problem.
Simplified Test Model
A simplified test model can quickly help identify many modeling problems in Abaqus/Standard. Consider using linear elements (C3D4 instead of C3D10), linear material properties, and coarser meshes for these initial debugging runs. Set the minimum step size reasonably high so a job with problems will fail quickly.
