Thank you very much for your answer.
So I have to make the simulation on the whole model (8/8) ? But then the
cost of the simulation will be 8 times more ?
And thus, I do not take benefit of the symmetry of the problem, or
I misunderstood something ?
It's the other way around. If you analyze a model without taking
advantage of any symmetry condition then you will have to pay the full
computational price to get a solution. This is the baseline case.
If, OTOH, you are able to take advantage of a model's symmetry then you
will be able to get essentially the same solution by analyzing an
equivalent model which is a fraction of the size of the original one.
In the case you've described, this model will be about 1/8th of the
original model's size. As a consequence, you might get the FEM solution
in about 1% of the time it would otherwise take to run the analysis.
Hope this helps,
