Hello,

 

I saw in a previous post, that the AIM can handle APDL commands (https://discoveryforum.ansys.com/t/g9hyb6c/export-deformed-geometry-back-to-cad). I have a simple command snippet from scratch. It creates a steel hollow section (shell elements) and adds a displacement load to one end, see attachment.

 

1) How can I run my commands? I copied the commands to the right sections (/PREP7, /SOLU, /POST1 etc.) but it does not work, see attached pictures.

2) Can I create the geometry in AIM with the help of APDL commands as well? Or I need a geometry from SpaceClaim etc. and only after that will be the commands available?

 

Regards,
Tamas

Hello Tamas

The main intention behind providing an option to add APDL commands in AIM was to access the functionalities of APDL solver which are not directly exposed in AIM. Please note that all APDL commands are not exposed in AIM application. For any setup in AIM, you need to have geometry and mesh. Since you mentioned that the APDL command snippet creates a steel hollow section (shell elements) and adds a displacement load to one end, this is all possible through geometry, mesh and physics task and doesn't need APDL commands.

Thank you Naresh Patre

 

1) But what about the mentioned previous post? (https://discoveryforum.ansys.com/t/g9hyb6c/export-deformed-geometry-back-to-cad). In that command snippet there are geometry and mesh related commands as well e.g. for setting element types (command "et") and creating areas (command "a"), see image below. How can these work then?

2) "Please note that all APDL commands are not exposed in AIM application." I saw in AIM HELP all of the APDL commands listed. Is there a list available containing only the APDL commands which are not restricted in AIM?

Hello Tamas

Though the commands that you highlighted in the script are geometry and mesh related, they are taking reference of underlying geometry and mesh. So, ultimately, you need to start with some geometry and mesh in Discovery AIM. Those cannot be done using APDL commands. 

The other reason that geometry and mesh can't be created using APDL commands is that for results evaluation, you need to reference the geometry location. It's not possible to reference the new elements that you create using APDL commands.

Regarding the list of supported APDL commands, I don't think there is any such list available. All APDL commands within the capabilities of Discovery AIM are supported.
