Reply To: Challenges with Importing Complex Geometries into ANSYS APDL

[me262]

I am now able to import the geometry files using both Parasolid and ANF formats, but I occasionally receive the following error:

*** WARNING *** CP = 122.922 TIME= 20:53:51 Line 47 on area 18 is not on the area within a tolerance. This area could have problems in future Boolean operations. (See the BTOL command).

Additionally, I am unable to use VGLUE to merge all volumes into a single entity. Visually, the geometry appears correct but is very small (approximately 20mm x 20mm x 20mm) and includes complex curves created with splines.

I've tried several approaches to resolve this issue, including:

• Adjusting scaling in ANSYS APDL and creating the geometry in meters to see if working with a larger scale would reduce tolerance issues.
• Setting the BTOL (Boolean tolerance) to a higher value, aiming to allow ANSYS to accept small gaps or minor misalignments between entities.
• Re-importing the geometry in different formats (Parasolid and ANF), but the issue persists.
• Inspecting and refining the geometry in SpaceClaim to check for any gaps or misalignments, followed by re-exporting with tighter tolerance settings.

Despite these efforts, tolerance issues continue, especially impacting Boolean operations. The main challenge remains the inability to use VGLUE to merge all volumes, which prevents me from progressing with the solution.

Any additional guidance on further steps or specific adjustments in APDL to enhance Boolean operation success and effectively glue the volumes together would be highly appreciated.
