GitLab now enforces expiry dates on tokens that originally had no set expiration date. Those tokens were given an expiration date of one year later. Please review your personal access tokens, project access tokens, and group access tokens to ensure you are aware of upcoming expirations. Administrators of GitLab can find more information on how to identify and mitigate interruption in our documentation.

Error in particle/ACMI_blockage interaction

A memory access error occurs when a particle interacts with the ACMI_blockage. MPPICDyMFoam is used.

A simple case and a log-file is included. There are two offset rectangular areas, connected by ACMI. Two particles are dropped in the upper rectangle. One particle falls through ACMI_couple and the other on ACMI_blockage. When the second particle touches ACMI_blockage, I get a memory access error.
