The command` itasca.dfn` works seamlessly in PFC3D. However, when I attempt to use it in PFC2D, I encounter an error: “AttributeError: module ‘`itasca`’ has no attribute ‘`dfn`’”. Could you advise on the correct usage of this command in PFC2D? Version Information: _PFC2D Version 7.00 Release 159_ Thank you. ---

Hello @pprasad, PFC2D 7.00.159 should have the dfn module automatically loaded. I just checked and I was able to produce a dfn without issue. Could you check if the module is loaded by to Tools \> Plugins and Load module with the Engine selected? ![image](https://canada1.discourse-cdn.com/flex031/uploads/itasca/original/1X/8b31d26faffb456e61917472dbfda41a4bc4ccbe.png) ---

Hello @dblanksma, I loaded the module manually and it works. Thank you.
