Difference between fdb and cdb

[Assiouras Nikolas 0]

Hello,

I want to use CAESES in batch mode (CAD generator)  so as to optimize a geometry. I read the open topic  but I am a bit confused. Can someone told me which is the difference between .fdb and .cdbc files, cause I can not find a way to export as .fdb my project. In addition, the difference of .fdbc and .cdbc with .fdb and .cdb is about the license type ?

Thanks a lot in advance!

Regards,
Nikolas.

Hi Assiouras,

it's quite simple: fdb is the file format of the CAESES4.x and older releases, while cdb is the current format of CAESES5.x. There is no backwards compatibility (you can open an fdb in CAESES5 and save it as cdb, but not the other way around), hence the different file type. In addition, anything with an additional "c" indicates a non-commercial license and therefore cannot be opened with a commercial license.

Best regards,
Heinrich

Hello,

I'm trying to open a .fdb file in CAESES5, but with no success. It simply doesn't show anything when I click it. And there's no option to open a .fdb file when the software is already open. How can I do it?

I've figured it out.
