Hello everyone,

I'm encountering an issue while trying to import a CAD geometry that I created in SolidWorks and exported in IGES format into ANSYS APDL. When I attempt to import the file, I receive the following error message:

Area list could contain multiple volumes.
Make sure areas enclose only one volume.

I have two questions regarding this issue:

1. Why am I getting this error message?
2. Is there a way to skip this error message in batch mode? I can skip it in interactive mode, but not in batch mode.

Here is the code I am using to read the geometry file:

/CLEAR

! /NERR,200,200,,0,0  ! Enable error handling
! /NERR,-1
! /EXIT,NOSTOP  ! Continue execution even if an error occurs

/AUX15                          ! Enters the IGES file transfer processor
  
IOPTN,IGES,SMOOTH             ! Help ensure that node features are correctly interpreted and included in the model
IOPTN,MERGE,YES                 ! Automatic merging is performed (default)
IOPTN,SOLID,YES                 ! Solid is created automatically (default)
IOPTN,SMALL,YES                 ! Small areas are deleted (default)
IOPTN,GTOLER,DEFA              ! Entity merging tolerance. Use system defaults (default)
IGESIN,'Path','IGS',' '        ! Reads a file containing IGES data and transfers it into the ANSYS database

/prep7
NUMMRG,ALL
VPLOT                           ! Display volumes

I will attach a picture of the geometry for reference.

Any insights or suggestions on how to resolve this issue would be greatly appreciated!

P.S. I have tried all the IOPTN options, but none of them worked.

Thank you in advance for your help.

Best regards,

You may be more successful if you export a Parasolid file from Solidworks to import into APDL using the PARAIN command.

Parsolid is ideal for importing solids because it is the native data format used in Solidworks.

Exporting IGES to import is only degrading the quality of the data.

It worked thank you so much!
