OptiStruct has proven to be a Robust & Reliable tool for Structural Analysis & Optimization **Rating:** 4.0/5.0 stars **Reviewed by:** Vishal B. | Mid-Market (51-1000 emp.) **Reviewed Date:** October 28, 2020 **What do you like best about Altair OptiStruct?** The strong points of OptiStruct are the Optimization Techniques like Topology, Topography, Shape, Size, Composite Shuffling. The Setup options available are vast & can be completely be controlled to get the Desired & Feasible Output. The structural analysis capabilities are on-par with other Solvers available in the market. **What do you dislike about Altair OptiStruct?** The major downside of OptiStruct is in the Analysis Setup. Lots of Cards are to be assigned for carrying out the Analysis. Remembering all the cards & assigning the required values is what i don't link about OptiStruct. The process managers need to be more robust to ensure that it can cater to all types of Analysis. **Recommendations to others considering Altair OptiStruct:** If you're looking for a Solver to deal with Non-Linear Implicit Problems, Dynamic Response Simulations as well as looking a tool capable of Optimization; OptiStruct should be a go-to tool. Another advantage is to maximize the benefit of HyperMesh for Pre-Processing as OptiStruct is integrated inside it. **What problems is Altair OptiStruct solving and how is that benefiting you?** The main types of Problems that I deal with in OptiStruct are as follows: Linear Static Analysis, Modal Analysis, Frequency response analysis, Random Response Analysis, Non-Linear Implicit Analysis, Structural Optimization Using Topology, Topography & Size Techniques. The main benefit is the capability to carry out both Analysis & Optimization in the same interface. The workflow to take a model from Analysis to Optimization is quite streamlined. This helped me a lot in carrying out Design Iterations & Optimize my designs. ### 6.
