TINA/Spice/LM5146-Q1-EVM12V: Output is dropping down to zero when connecting an ammeter at the output in TINA-TI

Part Number:LM5146-Q1-EVM12V

Tool/software:TINA-TI or Spice Models

Hello 

I am trying to simulate LM5146-Q1 EVM and the output is dropping down to zero when I connected an ammeter at the output. I had this same issue while simulating LM5145 EVM . I changed the analysis parameter and I am using the latest version of TINA. 

Thanks and Regards
