2D structural simulations

3D structural simulations

Topology optimization

Topography optimization

Full vehicle NVH simulation

E motor NVH simulation

High frequency above 2000 Hz need to established yet.

Simple energy Electric scooter is actually built on this for structural simulations.

Opitstruct is very easy to use solver and gives lot of options to solve complex engineering problems with accuracy. Help file of the solver has immense information and gives lot of in depth knowledge about the solver. Its robustness of solving problems on high performance computing clusters reduces solving time significantly. We use hypermesh as pre-processor and optistruct is the solver which is already integrated to it and thus allows us a smooth way to finish the work.

Optistruct has been significantly developed its capability with time. Sometime we face issues in solving highly non-linear implicit problems due to non-convergence of the model. Another challenge we face is in Modelling of non-linear spring elements and their behaviour .

Use it for structural engineering problems. It will certainly help .

We solve problems related to automotive structural engineering. We have worked on bus structures, fixture designs for automotive component and vehicle testing, vacuum tanks etc. We have carried out physical test co-relation activities also with the CAE results. Overall it reduces our time to come up with a solution .

Keynote talk on recent development in optistruct

Nothing. I found everything is good in the point of technicality

All kinds of structural problem from Automotive and biomedical domain

Easy to use

1st solver that I have learnt

Accurate for optimization

I don't think there is something to dislike there

Really a good, handy easy to learn and implement solver

Structural analysis

Linear analysis

Non linear transient analysis

Modal Analysis

Optimization

Easy to use tools to do compare during the iteration of part with the optimization of material, reduce the overall cost of Product without losing the strength of Product structure required. also, reduce development time &cost.

No downside.

Small & Medium companies are unable to take advantage of this tool due to cost factors also lacking for Skill manpower to use the same.

Excellent Design Optimization Tool. Very easy to use software & easy to implement with a short learning curve compared to others.

Material & Structure strenth Optimization.

Its easy to use and we can easily resolves errors which comes when Optistruct run is fired

Non linear analysis accuracy is less as compared with Abaqus.

Inertia relief analysis of same model was performed using Optistruct and Nastran, Result of Optistruct was showing very high stresses to that of Nastran.

Mostly, I do field failure correlation using optistruct.

Easily to prepare solver deck as compared with Abaqus.

Easy solver setup and reliable results especially for optimisation

For Non-Linear analysis the results are not so robust as comparison to other solver types

Must use tool for simplification of your CAE calculations

I mainly use Optistruct for Linear and modal analysis of metal and composite structures. Composite materials are very easy to analyse through Optistruct solver.

Altair Optistruct is a very advance Non-linear solver with most user friendly help documents. They have a very pro-active support team who are always available to assist for any queries related to their software. Optistrut is a very user friendly tool for design optimization purpose.

More stability can be added in the solver to output proper error reporting in case of debugging the model.

Non-linear analysis with material as well as geometrical problems.

User friendly, robust system, easy to learn, precise results, helpdesk support

Nothing at all. I couldn't identify any disadvantages

Comprehensive analysis solutions

It always comes with hyperworks license optistruct is the first commercial code in implementing topology optimization technology

Good for structural analysis

Difficult for dynamic problem like time dependent load

Good for optimization

Topology optimization and different optimization problems
