problem with cdb files from ANSYS 16 to be read in ANSYS 14.5

[ph47reey]

Hello all,

I have following problems. I meshed line, shell and point elements, saved it as a .db file in ANSYS R16, and use the command CDWRITE to create a .cdb and .iges file to be read in older version of ANSYS 14.5

with the input reading .cdb file there was no problem. I have the same mesh in ANSYS 14.5 as the one I have modeled in ANSYS 16.

Problem occurs when I want to modify/delete the line elements. ANSYS 14.5 cannot delete line elements (LCLEAR command), because they are associated with lines. However when I investigate by using the command LPLOT and LLIST there are no lines anymore in the model (no keypoints either, only nodes and elements)

I short, how can I dissociate line elements from the lines that are no longer there in the model?

Lot of thanks for your help!

[SOLVED]

I think I found what I've done wrong:

instead of reading the files via "File/Read Input from...", one should utilize the command CDREAD or UI: "Preprocessor/Archive Model/Read". When there specifiy the path for both the .cdb and .iges files and voila!
