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.

Thanks for the response @Fangjun Jiang.

I was actually using the "From Workspace" block since the beginning and had infact put the same input configurations [tout, u]. I had also specified the same in the "Data Import/Export page" of the model configurations, still I was getting the error.

However, I tried using the inport block, and it worked just fine.

Thanks a lot for your help.
