Attaching Properties to 3D Mapped Meshes

Altair Forum User

Recently been playing around with using 2D automeshes, and then mapping the resulting meshes to mappable solids.  

 

Before this, I was using volume tetrameshes on complete solids without having to split them up (required for mappability).

 

I am trying to assign the property (containing material properties) to the elements now, and I have done this in two ways: 

1) assign the property to the component containing the mesh

2) assign the property to the elements directly.

 

It seems that the few CTRIA3 elements in the mesh did not like the property, however, and this is causing the analysis to crash before it even starts.

 

 

Attached are the model and the .out file that is obtained from trying this analysis.

 

Any thoughts?

You have some 2d Ctria elements which needs property.I believe you would have use 2d elements to generate 3d elements.After deleting tria3 element it will run.

Delete elements :by config:ctria: Delete

Hey Rahul,

 

Thanks for the tip!  I redid the 2D automesh and made sure it was quads only, so no tria elements were there the 2nd time around.  

 

I also deleted the 2D mesh completely so there was no confusion for the solver.  

 

Attaching the properties after that and running the analysis + later on the optimization worked fine.
