I have created file.elem and file.node file from ansys pre-processor. I tried to read these two files in STAR-CD using import grids with ansys option

ansy,file.elem,file.node

I got following error message.

**************

READING ANSYS ELEMENTS FROM file.elem READING ANSYS NODES FROM file.node

ERROR ELEMENT 1 HAS AN IMPROPER NUMBER OF NODES

(DOES NOT MATCH EXISTING DEFINITION IN CTABLE)

1 ELEMENT READ. MAX ELEMENT IS 0 6265 NODES READ. MAX NODE IS 6265

*****************************

element 1 has following list from ansys

1 72 73 3 0 0 0 0 1 1 1 1 0 1

Can you help me why i am getting such an error.

I guess, you have to define the proper cell type in StarCD before importing the grid. The element looks like a shell with cell type 1. So the cell type 1 in StarCD should also be of type shell.

Hope that helps

Cheers, Andreas

thank you andreas, this has helped me to import.

one more question, does STAR CD retain the material type, element type of ANSYS in STAR-CD so that it will be easy for me to defien material properties and boundary conditions.

As far as I know, the interface can only handle grids (cells and vertices). You have to redefine your properties and boundaries. I'm not sure if you could save the ansys properties as a coded file and import it into Star. I never tried it. I just use the interface to pass along the grid between Ansys and Star.
