Cyclical Dependency in Operations

Platform: Process Simulate

The operations depend on each other in a cycle, so Resolver cannot determine a valid order to execute them. The export is blocked until the cycle is removed. This usually points to an unexpected modeling structure; if you cannot identify the cause, contact support with the study and logs.

Dialog shown in Resolver​

The following operations are forming a cyclical dependency: Operation: {operationName}, Parent: {parentName}

What you can do in this dialog​

  • Can you continue export? No
  • Buttons in the popup: OK
  • What happens next: The export does not continue until the cyclical dependency is removed.
  • Next step: How to fix it

Impact if you continue​

Export cannot complete while operations form a cycle. Resolver has no valid execution order to build from a circular dependency.

How to fix it​

  1. Open the operations listed in the dialog and review how each one depends on the others (parent operation and any ordering links).
  2. Break the cycle by removing or redirecting the dependency that closes the loop, so the operations form a one-directional order.
  3. Save the study and re-run export.
  4. If the operations look correct and the cycle is unexpected, contact support and attach the study and exported logs.
