While simulating model in Simulink I got error as "External input specified in the Configuration Parameters dialog box on the Data Import/Export page (or as an option to SIM command) to a model containing no root level input ports"

You specified input data, but there is no root level input ports, which means no input data is needed.
If you've done this manually or inadvertently, press Ctrl+E, select "Data Import/Export" on the left, un-check "Input" on the right.
