Impressive multiphysics capabilities **Rating:** 4.0/5.0 stars **Reviewed by:** Andreas O. | Naval architect, Small-Business (50 or fewer emp.) **Reviewed Date:** August 04, 2025 **What do you like best about Altair SimLab?** I like the fact that it is a very diverse simulation environment, with lots of different software integrated. The ability to couple different solvers to run multiphysics simulations are valuable to us. I have mostly used SimLab for fluid-structure interactions, coupled thermal solutions and smoothed particle hydrodynamics, as well as some preprocessing meshing, and it has served me and my colleagues well so far. It is a software under continuous development, and new features are added upon each release, which is good to know. The user interface is also neat and easy to use, and the support from Altair is great if you need additional help. The geometry preparation is also very helpful and quite extensive. Lots of stuff can be done directly within SimLab instead of going to a dedicated CAD software. I have only used parts of its potential, but I see everything else it can do within electromagnetism, fluid, thermal and structural analysis. When we need to do more complex coupled simulations it is our go to software. **What do you dislike about Altair SimLab?** As with all software there are some drawbacks. The example database could be bigger and more updated, particularly for the coupled analyses, and the documentation could be easier to navigate. There have also been instances where the software has freezed, but that is not often, and could be a hardware issue on my end as well. For some reason it is not possible to undo and redo actions within SimLab, which I don't understand why. It is quite annoying. **What problems is Altair SimLab solving and how is that benefiting you?** The ability to couple solvers and run multiphysics simulations is what benefits us and makes this software stand out. ### 2. SimLab offers a streamlined and user-friendly environment with powerful integrated analysis tools **Rating:** 4.5/5.0 stars **Reviewed by:** Farhan S. | Project Engineer , CAE, Small-Business (50 or fewer emp.) **Reviewed Date:** August 01, 2025 **What do you like best about Altair SimLab?** What I like best about SimLab is how seamlessly it integrates everything into one platform. Having used HyperMesh for years, I found SimLab’s user interface comfortably familiar, yet more intuitive. The meshing process is streamlined, and geometry handling is significantly easier. What really stands out is the ability to perform all types of analyses—implicit, explicit, and CFD—within the same environment. There's no need to switch between different software tools, which makes the workflow much more efficient and user-friendly. **What do you dislike about Altair SimLab?** One aspect I find challenging in Altair SimLab is the midplane extraction for injection-molded plastic parts. These components often have intricate geometries, and the automated midplane generation doesn’t always handle the complexity well. It requires a lot of manual intervention to get accurate results, which can be time-consuming. Having more control and flexibility over midplane meshing would significantly improve the experience for users working with detailed plastic geometries. **What problems is Altair SimLab solving and how is that benefiting you?** Altair SimLab enables rapid design feasibility assessments during the early stages of development, while offering the convenience of performing all types of analyses—structural, thermal, CFD, and more—within a single unified platform. This significantly streamlines the workflow and enhances productivity. ### 3. SimLab: Almost everything is on the same platform **Rating:** 4.5/5.0 stars **Reviewed by:** Francisco Javier R. | Professor, Higher Education, Mid-Market (51-1000 emp.) **Reviewed Date:** July 16, 2025 **What do you like best about Altair SimLab?** I typically use SimLab for structural and fluid simulations. I have also used the software to create topologically optimized shapes. The major advantage I see in this software is its multiphysics simulation capabilities. It is so simple and intuitive to use. There are a lot of tutorials that help me create my own simulations. Additionally, forums and support tickets complement the help process very well. **What do you dislike about Altair SimLab?** Before starting a simulation, I used to read the theoretical documentation to make sure I knew what I was doing in the software. However, SimLab and its solvers do not have enough of this type of documentation. Moreover, the tutorials are almost always outdated, and sometimes something does not work properly in the current version of SimLab because a button could have been changed or a feature could have been removed. **What problems is Altair SimLab solving and how is that benefiting you?** I have used SimLab to solve complex engineering problems through simulation, including structural (static and dynamic) and fluid (stationary and transient) simulations, as well as topology optimization for fluids and solids. This software has benefited me by making these complex simulations accessible and manageable through its simplicity, intuitive use, and strong support system. ### 4. Automatic meshing of complex assemblies with SimLab **Rating:** 4.5/5.0 stars **Reviewed by:** Antti M. | Senior expert, Mechanical or Industrial Engineering, Enterprise (> 1000 emp.) **Reviewed Date:** August 04, 2025 **What do you like best about Altair SimLab?** Very powerful tetrahedral meshing algorithm that ensures high quality and minimizes pre-processing time. It can read meta data like solid body and surface naming made in CAD software. Naming and colors are transferred to SimLab in general parasolid format. Pre-processing can be automated by using Python interface. **What do you dislike about Altair SimLab?** The Python interface could be better. There is still XML format inside python functions. **What problems is Altair SimLab solving and how is that benefiting you?** Meshing and setting up finite element models for structural analysis and computational fluid dynamics. ### 5. Functions not adopted **Rating:** 3.5/5.0 stars **Reviewed by:** Vitaliy F. | Entwicklungsingenieur, Enterprise (> 1000 emp.) **Reviewed Date:** August 14, 2025 **What do you like best about Altair SimLab?** Easy installation and user-friendly operation. A wide range of different modules. Online help and tutorials. Community and support. **What do you dislike about Altair SimLab?** In a new update, some functions are not adopted. For example, version 2025.1: - automatic conversion of the decimal separator "," to "." no longer works; - 3dConnexion mouse cannot be integrated. **What problems is Altair SimLab solving and how is that benefiting you?** CFD Simulations Coupled EDEM Simulations With Altair SL, these business challenges can be solved. ### 6. Can do a lot but is unnecessarily complicated **Rating:** 2.5/5.0 stars **Reviewed by:** Stephan B. | Berechnungsingenieuer, Enterprise (> 1000 emp.) **Reviewed Date:** September 16, 2025 **What do you like best about Altair SimLab?** The possibilities to connect. You can really reach the network you want. **What do you dislike about Altair SimLab?** Quickly "briefly" looking at a component is not possible. Analyses with NL contacts are EXTREMELY complicated (compared to Ansys Workbench). Support is very tedious. **What problems is Altair SimLab solving and how is that benefiting you?** (Nonlinear) structural analyses of steel components. ### 7.
