how to refer to the global model in the input file of submodel when using submodeling?

Hi,

I'm recently trying to use the submodel technique in ABAQUS. When using this technique, we need to refer to the output file of the global model, in the inp file of the submodel, so that the information in the global model can be used. When using the CAE it is quite easy to refer to the global model, but now I want to refer to the output file of the global model directly in the inp file. I searched through the ABAQUS manual, and found that the input file usage for this function is :

abaqus job=submodel_input_file globalmodel=global_results_file or global _output_database

But after I added this line into the inp file of submodel, I still got the error information that :The result file containing the global model file was not specified.

In this case I think I might placed the line in the wrong place in the inp file. Does anyone know where I should place this line from ABAQUS manual in the inp file, to be able to refer to the global model output file?

Regards,

George
