Hello

What is the purpose of this Generative Structural Analysis Fabric Deformation  Amplitude option ( http://cjoint.com/?DHydlQ9CDbN)

Thank you

Hello

If it's like in SolidWorks, wouldn't it be the "visual" deformation coefficient?

When you have done your simulation calculation, your part is shown to be exaggeratedly distorted. This coefficient is there to adjust this deformation to make it coherent and understandable.

For example, a recessed plate on one side with a load on the other, with a low coefficient, you will see on the screen a deformation of a few millimeters from the end. With a high coefficient, you will see a curved flat!

This coeff corresponds to the amplification made on the visualization of the deformation in order to better see the appearance of the deformation of the part.

A scale 1 representation of the deformation would not be different from the original mesh. Basically, without this coef, we wouldn't be able to understand how a part is deformed.

In the example  the coef is in 10^8 which suggests that the deformation must be very very small.

Hello

This is the deformation coef seen on the screen, in general it is enormously amplified so that we can see where the piece is deforming and where its weaknesses are.

If the factor is close to reality we don't see anything in some cases, when the part is at the resistance level. in short, take into account only the result of the calculation.

Well done video on the subject:  http://youtu.be/Whr6bu2n1iY

Good luck.

weird the +1 on this question...^^

 

+1 Benoit ;)

Thank you for your answers what I don't understand is: what relationship is there between this deformity and the application of loads,  it's not random that we choose the factor and what are the criteria needed to choose the factor?

Thank you

There is no real criterion. This coefficient has no influence on the results of stresses and displacements.

It only makes it easier to visualize the deformation of the part. The lower its value, the less you will see the deformation, and therefore will be as close as possible to what will happen in reality. The higher it is, the more exaggerated the visualization will be (even absurd in some cases) but it will allow you to better understand the behavior of your part under load.

This coefficient will therefore certainly have to be changed for each part. But it's still a tool with no action on the result.

So validate one of Benoit's answers as the best.
