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

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

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

(OP)

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!
