How can I resolve this error ?
显示 更早的评论
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.

What should I do if I actually need input data for my Simulink model from the base workspace, and I'm still receiving the same error?
Basically, I'm generating a cosine wave (u) in MATLAB, using a Time vector (tout) that was generated by a simulink model (model_A, say). I want to send this cosine wave to another Simulink model (model_B, say) for further processing.
Here's my MATLAB script:
% tout is a variable generated in the same workspace, from simulink model_A
u=cos(tout);
sim('model_B');
Command Widow Error:
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
Thanks.

In this case, you need to have a root level Inport block. Then in model Configuration Parameters, Data Import/Export, check Input, [tout,u].
This is as if you are connecting the base workspace data [tout, u] to the root level Inport block.
Another way is to use a "From Workspace" block in the model and specify the data as [tout, u]. Then you don't need the Inport block.

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.

Add an Import block to the root level of your model
