Ansys LS-DYNA Reviews

LS-DYNA's standout strength is its explicit dynamics solver, which excels at simulating extreme, short-duration events like crashes, impacts, and explosions with remarkable accuracy. What makes it truly powerful is its massive parallelization capability — it scales efficiently across hundreds of CPU cores, dramatically cutting down solve times for complex, large-scale models

The biggest downside of LS-DYNA is its steep learning curve — it's far from beginner-friendly, and even minor mismatches in card definitions or material parameters can produce completely wrong results without obvious warnings. On top of that, it carries a high licensing cost, making it hard to justify for smaller firms, and much of the advanced knowledge is locked in tribal wisdom among experienced users rather than accessible documentation

I use it to solve crash simulations clients designs related to automobile industry

LS-Dyna is an industry-wide, well-known software for its explicit-domain simulation capabilities, serving industries such as automotive, aerospace, blast and mining, heavy equipment, chemicals, and more. I especially like LS-Dyna’s multiphysics simulation capability, along with the reliability and accuracy of its simulations. It also offers broad support for many element and material types, including options for degradation and failure-propagation behaviors.

LS-dyna has wide variety of the material library along with various cards to help stabilizes the solution and achieve the convergence. That also becomes its downside as minute variation or definition mismatch in the cards can results in completely useless results. Unless and until you know how its each parameter works and how to use each card its really difficult to get appropriate results. Its not at all beginner friendly, You can not directly start learning LS-dyna without any prior understanding or training in FEA domain and tools like, ansys, abaqus, nastran or optistruct.

We are using Ansys LS-dyna for the virtual simulation and validation of the plastic components used in Automotive and Electrical industries, which saves our cost on physical validation and reduces the cycle time of design validation by implementing multiple iterations in virtual platform. this is huge cost and time saving for our industry.

While the Dyna code has evolved, Oasys suite has remained concise and logical to use. It provides Vectayn Ltd the confidence to build stable models and checking prior to submitting the job. Also, it is now easy access to all packages within the suite which provides an all round suite. The Oasys Team listen to our requests and suggestions, incorporating them into next releases. As expectations of analysis have changed, from a bolt on to vehicle programmes to a central process in design development, Oasys Suite has continued to evolve to allow analysts to work efficiently. It is clear that the development team have input from engineers working on live programmes and experiencing what users actually need.

No much to be honest. Prices are creeping up and the license term isn't as flexible as once was.

The advancements in Reporter to incorporate the legal crash protocols.

Sometimes simple things are most effective. Recently we learnt about Panel positioning in Primer.

Ansys is a great program for mechanical analysis.Especially meshing and force capabilities is very great and there are a lot of options. Besides, UX is very useful for new users.

Basic modelling tools and material library need to improve

As a engineer I need a lot of mechanical performance calculations.

I have used Mechanical APDL interface of Ansys and LS-Dyna as a solution engine. I could obtain precise results from very difficult non linear dynamic FEA models.

I could not find implicit dynamics settings for slow metal forming simulations. I spent really long simulation time for the results from explicit dynamics analysis.

I tried to solve mostly roll bending of metal plates into circular geometry, it was impossible without LS-Dyna solver.

Ansys LS-DYNA allows you to simulate and analyse various complex problems it has easy to use interface with so much detailing wich makes it easier for the user to do enhanced problems.

i couldn't say anything wrong with the software because it was so comforting to use, but the user interface could be much more efficient and simplistic design making it even more comfortable for the user.

Ansys LS-DYNA solves complex crash analysis problems for engineers. It is used to simulate the 3D Model designed for understanding its characteristics which when crashed.

Results of my analytical calculations are matching exactly with some tolerance with Ansys LSDyna

I don't find anything in Ansys ls dyna about to dislike

Recently solved problem on simulation of ocean waves on pumps. We are able to solve this with ansys hydrodynamic diffraction and with the help of hydrodynamic response analysis. Using Ansys from last 7 years.

Software is so easy to understand and learn. User friendly with good GUI. We can solve larger probablems very easily.

It would be better, if we get some post processing tools to view in detail.

Am using LS dyna, to check the crash and Safety performance and to find crash worthyness. We had some other softwares but those are not much easy as this.

The way it helps model dynamic scenarios to analyse different real life situations in an intricate manner.

The software is heavy for ordinary laptops.

We modelled vehicle crash scenarios for SAE BAJA competition and they were very accurate.

I did my final year thesis in Ansys LS-Dyna. Ansys was a user friendly software and every tool was easily accessible. The large variety of analysis tools have us upperhand in our project.

Since I had a very good experience I would say there is nothing really to improve from my point of view. The user interface could be much better when compared to other softwares

For my final year thesis
