Problem importing .cdb file.

[manarshhjot]

I am trying to import a mesh from an existing .cdb files. The file contains the information regarding mesh and BCs. I have used two methods.

If I use mapdl.input(<file_name>), I receive the following error:

\n\n *** ERROR ***                           CP =       0.906   TIME= 05:42:05\n The element option SOLID185 was either not ordered with this ANSYS installation or the appropriate product was not selected for this session. Contact your ANSYS support person for more information.

The second method I used is mapdl.cdread("DB", <file_name>). The statement is executed correctly but the next command mapdl.db.max_num gives the following error:

Hi @manarshhjot can you please verify the actual command you entered asmapdl.db.max_num is not a valid command. I'm guessing that maybe you really entered mapdl.db.elems.max_num but would rather see proof (screen shot etc) of what was entered.

Also, use the prep7 cdread command to read in the cdb file and not the input command, as good practice.

@manarshhjot any updates on this?

[manarshhjot]

@germa89 mapdl.db.elems.max_num worked

Marking this as the answer.
