Radioss analysis error

Altair Forum User

Hello,

I am a novice level Hyperworks user.

I am trying to run analysis on a part I designed in Solidworks. It is actually a sub assembly of two parts. It was converted to an IGES file and imported as such into Hypermesh. I performed a mixed type of tetramesh on it and after defining the material property as Aluminum, part property Solid, defining the load collectors and the load steps.

When I use Radioss, it gives me the following error :

'

A fatal error has occurred during computations:

Element # 57457, element type TETRA.

RAM: 171 MB total, 546 MB used.

Data arrays: 161 total, 126 allocated.

DATA SET size 26 MB, ram_disk 2 MB '

From my understanding, it has something to do with the mesh element numbered 57457. I am unable to find where that element is located. I did try a number of automesh and element cleanup tools, as well as tried to remesh with different types of meshes and sizes.

However, I am stumped. Any insight on this issue is appreciated.

Thanks.

You should check the elements from any errors from elem check menu

Check edges, connectivity, duplicates etc. and then you could be sure of that your model is ready for sol'n.

Also you should apply some boundary conditions.

You could find the element and mark it via find menu (find > elem > enter id)
