Dear Engineers.

I am currently working on a simulation project on Air-levitation platform, however when I am trying to use ICEM for mesh generation, I got the following error:too many nested evaluations (infinite loop?). This occurs while I am linking the edge of the blocks to the curve of the geometry. Why would this happened and how can I fix it or avoid it? Thank you very much!

PS: I am using Ansys 2019 R1

This error message in ICEM, encountered while linking block edges to a geometric curve, indicates a potential issue with the way you're defining the link. Here are some possible causes and solutions:

Causes:

Circular Dependency: The linking process might be creating a circular dependency between the edges and the curve. This could happen if the definition of the link relies on information derived from the linked entities themselves.
Incorrect Selection: You might be inadvertently selecting multiple edges or curves during the linking process, creating a loop.
Software Bug (Less Likely): While less common, there's a slight chance this error could be caused by a bug in the specific version of ICEM you're using (Ansys 2019 R1).

Solutions:

Simplify Linking Logic: Review how you're defining the link. Avoid relying on information from the linked entities within the link definition.
Double-check Selection: Ensure you're only selecting the intended edge and curve during the linking process.
Check for Over-Constraints: Make sure the linking doesn't create any over-constraints on the geometry. The linked entities should have the necessary degrees of freedom to maintain a valid mesh.
Try Alternative Linking Methods: Explore alternative ICEM linking methods like "Match" or "Project" to achieve the desired connectivity.
Consult Documentation and Forums: Refer to the ICEM documentation or online forums for specific examples and troubleshooting steps related to linking edges and curves.
Consider Upgrading (if applicable): If you suspect a software bug, consider upgrading to a newer version of ICEM if feasible. Newer versions often contain bug fixes and improvements.
