Hi,

 

What type of data do you have for the material?

 

What type of analysis are you trying to perform?

I WANT TO DO A WEIGHT REDUCTION IN HYPER MESH OPTISTRUCT.

I HAVE E, NU, AND RHO FOR ABS MATERIAL. WHICH CARD IMAGE IS USED IN MATERIAL PORTION

 

Altair Forum User

I have the same question, did you resolve?

Altair Forum User

HI,

 

Since you have only E, NU and RHO use MAT1 card

I would like to know the meaning of the abbreviations that appeard on the load colector card image. For instance there is : EIGC, EIGRA and so on. 

There is a pdf describing all this abbreviations ?

Hi @Stefanie Carvalho

 

EIGC: Defines data required to perform complex eigenvalue analysis.

EIGRA: Defines the data required to perform real eigenvalue analysis with the Automated Multi-Level Sub-structuring technique.

Thanks! 

One more question: when I import the geometry from solidworks do I have to create a solid of it before meshing it or I can simply mesh on the geometry?

Hi @Stefanie Carvalho

 

If your model is a sheet metal or a platic component, please extract mid surface and start meshig with 2D elements. Otherwise you can mesh with 3D elements.
