Axisymmetric model

ivanIEV

Hi everybody,

I am relative new work with Altair products, so don't judge me:)

I am curios, is it possible to make axisymmetric model in hypercrash/radioss. For example, I have a short pipe of variable cross-section, is it possible to simulate it in 2D axisymmetric mode? Are there any examples?

Thank you in advance!

Hi,

For a case like in which the geometry, loadings, boundary conditions and materials are symmetric with respect to an axis is one that can be solved as an axisymmetric problem. If your case is similar to this you can choose this option.

In order to activate an axisymmetric analysis Use N2D3D = 1 for /ANALY card in the Starter file and ensure that the elements are defined in YZ plane and their normals have to be in the positive X-position. Model with shell elements and update the element type as Quad and assign solid property.

I recommend you to model the same in HyperMesh rather than HyperCrash and solve in RADIOSS.
