Importing an APDL model into Workbench can be very useful. This article outlines the steps to import a model.

Step 1: Run the APDL program in ANSYS Classic and use the cdwrite command to output a cdb file. The format for using the cdwrite command is as follows:

CDWRITE, Option, Fname, Ext, –, Fnamei, Exti, Fmat

Writes geometry and load database items to a file.

The cdwrite command help is as follows:

The following example generates a mesh file only (no associated geometry):

CDWRITE,DB,myfilename,CDB

However, usually you can set it up as follows to ensure that your APDL model can be fully imported into Workbench.

CDWRITE, All, myfilename, CDB

Step 2: Drag an appropriate analysis system, such as Static Structural, into the Project Schematic. Next, drag the Setup cell of the External Model to the Model branch of the Static Structural system.

Step 3: Right-click the Setup cell of the External Model system and choose Edit or just double-click Setup.

Step 4: Browse to the cdb file that you generated in Step 1.

Step 5: Right-click the Setup cell of the External Model system and choose Update.

Step 6: Link the Model Cell in the Static Structural system, right-click, and choose Properties.

Step 7: In the Properties window that opens on the right, choose the Length Unit as in the CDB file and indicate whether the analysis is 3D or 2D. Nodal Components will be included by default and might be desired to use as Named Selections.

Step 8: Double-click the Setup Cell in the Static Structural system, and now you’ll see the model in the APDL has been imported to Workbench. Good Luck!
