Troubleshooting why a program closes after disconnecting RDP

Question

I use RDP to run a program (ANSYS Fluent) on two headless workstations (win7 and Win10). If I disconnect (not log off) from the RDP session Fluent is immediately closed. However, all other programs (even other ANSYS programs) continue to run without problems.

How can I troubleshoot this problem? Is there a way to log all commands such that I could disconnect the RDP, reconnect and view what is actually happening during that time?

Open gpedit.msc
  
  Browse to Computer Configuration --> Administrative Templates --> Windows Components --> Remote Desktop Services --> Remote Desktop Session Host --> Session Time Limits.
  
  Enable the "Set time limit for disconnected sessions" and set it to "Never".
  
  [I didn't have to do this [next step] but here for completeness]
  
  and change the Local Security Policy under Local Policies -> Security Options -> Interactive logon: Do not require CTRL+ALT+Del" to "Enabled", the problem disappears.
