"Efficient and Accurate Crash Simulation Software Radioss"

4.5/5

What do you like best about Simcenter Radioss?

What I like most about Altair Radioss is its robustness and accuracy for crash and impact simulations. As a crash simulation engineer, I use explicit finite element analysis on a daily basis, and Radioss provides reliable results for highly nonlinear events involving complex contact interactions, material behavior, and large deformations.

What do you dislike about Simcenter Radioss?

One aspect that could be improved in Altair Radioss is the learning curve for new users. Due to the large number of cards, parameters, and solver options available, it can take significant time and experience to fully understand and use the software efficiently. In addition, debugging model setup issues can sometimes be challenging, especially for complex crash models. Review collected by and hosted on G2.com.

What problems is Simcenter Radioss solving and how is that benefiting you?

Altair Radioss helps us predict the behavior of products during crash and impact events before physical testing. In my daily work, I perform simulation-driven predictions that allow us to evaluate structural performance, identify potential issues early in the design process, and optimize designs before building prototypes.
