I created a Craig-Bampton dynamic super element as per methodology described in "SACS Dynamic Superelement" document.
I created a wave response file so as to have be able to create a reduced force vector.
Spectral check is directly done in the listing file of the super element calculation, however I would like to proceed with a spatial check of my super element.
Thus, I would like to compare interface joint displacement of the super element while I apply the same wave on it than on the full model (a jacket).
However, I cannot find a wat to import the Craig-Bampton super element into SACS.
Could you please explain me how to proceed ?
Dynamic superelements are not yet supported as input for SACS analyses. They are primarily intended for interoperability with other analysis programs. You will need to perform the dynamic analysis with the full structural model.

Hi, Guillaume Luria. I am studying dynamic superelement nowdays. In terms of spatial check, I think SACS itself can give the answer, without the need to import Craig-bampton super element again into SACS. In the process of wave response, you calculated the response of the full model. Then, in the process of dynamic superelement, you can get Time-History for Superelement in the listing file, which I suppose is the response of superelement.
Finally, the above two datas can be compared, and the good agreement in the target point can guarantee the spatial convergence.
