Sorry we have 2 "heartbeats".
(1) While the client machine is connected to the license manager is will send heartbeat every 6 hours after the last checkout "if it is still using the license". If the client detects a network issue it will sync and try to reconnect with the license manager. Otherwise, the simulation job might get terminated and will have to be run from the start.
(2) The license manager sends a heartbeat to the client machines 15 minutes after the clients' last checkout. Then 2 hours after - where It checks in the "Lumerical license feature" if there is no response. Sorry, I think the 90 minutes idle timeout is for some other Ansys products.
Hope this helps.
