Error in importing to flex body
Dear Friends,
I am doing simulation of MBD. Till now I was doing Rigid body dynamics but now I have started with small mechanisms with flexible body so after meshing the body when I tried to upload there was an error persisting. So when I queried in the MV forum they directed here. I am attaching the error please help me out with this issue.
" *** See next message about line 253 from file:
C:/Users/kiran/Downloads/four-bar-mechanism-11.snapshot.11/Connecting rod FEM_prp.fem
"CTRIA3 20 0 110 39 109"
This line was interpreted as:
253:CTRIA3, 20, 0, 110, 39, 109"
Thank you

Hello Kiran,
The error from OptiStruct on the TRIA element occurs because there's no property assigned to the element. Import this flexible body .fem in HyperMesh, make sure that the components with those elements in them have material properties assigned to them and export the .fem model again.
To do this, create a material, create a PSHELL property and link to that material, and then go to the component containing the tria elements, and link to the property. The elements should have something other than 0 in the third field, it should be the property ID.
Thanks,
Rob
Ok thank you for the information from your side, is it possible to get some meshing tutorials. Since I am having a solid body and have to move on with PSOLID type so I am not much renowned of how to perform that so it would be of great help if you could explain me.
Thank you

Hi Kiran-
Meshing tutorials for HM for solid mesh can be found in the documentation and the tutorial models can be downloaded from Altair One or are included if the help is installed locally on your machine. You can access documentation by pressing F1 in HyperMesh and going to HyperMesh -> Tutorials. These tutorials may help with solid meshing:
HM-3100 - Automesh (for 2D meshing)
HM-3200 - Tetrameshing
HM-3220 - Create a Hexahedral Mesh
Thanks,

Thank you very much for your solution and I did the same way and I have got the thing correct
