Topography optimization

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 .

Altair OptiStruct is a best software for the performance of FEA analysis. It is very easy and accurate. It help to provide all the things in single tool.

Less accuracy for the Non linear analysis.

It help us to perform best and accurate for the analysis.

Keynote talk on recent development in optistruct

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

All kinds of structural problem from

.Easy to use

1st solver that I have learnt

Accurate for optimization

I don't think there is something to dislike there

I have used Optistruct for the topology optimization of one part of the complex dynamic mechanism. The step by step approach helps to provide detailed boundary condition of the physical problem. Simulation results provide enough understanding of the physical effect and stress generation in different connections.

For meshing ane material properties, Altair provides various options for different types of elements.

Solving different errors due to the mess quality is time-consuming. A thorough understanding of the theory behind the FEA helps to solve different errors. Although there are software available that solve the problem without even manual meshing, I don't prefer the same because there are high chances of error if something goes well particularly in the complex mechanism.

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.

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.

Ease of usage of tool and flexible with interpretting the tcl language and make the alter as required.

Need to look more improvement in dynamic analysis and PSD results, as nastran finds its place as replacement for optistruct

I recommend optistruct for usage by other customers for the ease of usage

Optistruct is compatable to perform Static linear and non linear Analysis, dynamic analysis,Random analysis and solver does these with less amount of time and with minimum input parameters.

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.
