How can I inject exported current from a older file to a new metallic rectangular surface?

Suppose I have some exported  current values only from the metallic lines from any  antenna model.  I exported those current values in separate file. Next I created a completely new file in Feko  which contains a metallic rectangular planar surface only. Now If I want to apply those exported currents to my new rectangular planar surface structure by calculating the same metallic are of my previous antenna model then how can I apply those exported current?

Could anybody help me out about this?  Thanks in advance!

    Dear Srabonty

    This should be possible using the Solution Coefficients (*.sol) file in Feko. Note that the solution coefficients represent the surface currents.

    In your original antenna model you should add a Model Decomposition request to write out the *.sol file:

    You could then import these into your next model as an equivalent source:
