ACP has the following known limitations. Note that feature-specific limitations are often documented with the corresponding feature description throughout the ACP user's guide.
Support for Unicode
Unicode is supported in ACP except for these features:
Names in CDB Export: Unicode (non-ASCII) characters in an ACP model are converted to underscores when the model is exported as a CDB (coded database) file. This can cause two different names to become the same after the conversion.
ACP issues a warning when a duplicate name is exported. This check for all names that are considered equivalent in Mechanical APDL is stricter than the check for the conversion from Unicode to ASCII.
File Paths in ACP to Mechanical APDL Workflows: In an ACP to Mechanical APDL workflow within Workbench, the file path of the Workbench project must not contain Unicode (non-ASCII) characters.
Laminate Plot Labels: The labels in the laminate plots of stackups, sublaminates, and sampling points support only a limited set of Unicode.
User-Defined Plot Text: The user-defined text in user-defined plots supports only a limited set of Unicode.
Ply Books in PDF Format: When generating a Ply Book in PDF format, you must adjust the font in case unsupported characters are used.
Composite Failure Tool for Migrated ACP Projects
The Composite Failure Tool in Mechanical can only be used in migrated projects once the ACP-Pre Setup Workbench cell has been updated.
Coordinate System Naming for Migrated ACP Projects
In Version 2019 R2, naming is maintained when coordinate systems defined in Workbench are transferred to ACP as Rosettes. (See Rosettes.) When migrating projects from previous versions, the Oriented Selection Set Properties may lose the Rosette link due to the renaming. This will require lay-up definitions to be updated manually as shown in Figure 1.1: Oriented Selection Set Properties. For more information on migrating projects from previous versions, see Migrating ACP Projects from Previous Versions.
Export System(s) and Import to Workbench
The Export System(s) and Import of Workbench projects are not supported for ACP Systems. With this current limitation, the imported ACP systems cannot be updated correctly after import.
Parameters
In ACP, Parameters, and how they are handled by the Parameter Manager, have certain limitations. See the Parameters section for additional information.
Options for Objects with the Same Name
The application allows you to create objects with the same name. However, there are certain property specification and graphical selection limitations for this scenario. Based on the object type, you may not be able to define the properties to include objects with the same name. For example, you cannot define Sub Laminates using a Fabric and Stackup that have the same name.
