boundary condition problem
 

Hello to everyone,

I perform a simulation with two configurations (two analysises) where each configuration has a different domain. I would like to use at the second analysis as boundary condition an expression with the calculated data from the first analysis (the shear stress and the concentration of a variable).
Does anyone have an idea how to do this?
When i try to use an expression with this variable to the second analysis an error like "this variable doesn't exist" appears.
Thanks
