Hello, I need help with my script on Ansys APDL, if possible.
I'm working with two different loads applied to a tube and because of that I need to perform two non-linear analyzes (Geometrically and Materially non-linear Analysis with Imperfections - GMNIA) in sequence.
Basically I would like to simulate a bar of an offshore jacket type truss (annex), the structural elements are under lateral external pressure and soon after the equipment will be installed, introducing the effect of axial compression.
(i) First external lateral pressure
(ii) Second Axial Compression
In the case of simulation:
The first analysis will be the lateral external pressure, coming from the form obtained from the 1st buckling mode and the geometric and material nonlinearity will be added. My intention at this stage is just to obtain the deformation and stress arising from any pressure. The maximum value already determined in another analysis.
The second analysis will be in the sequence of the first analysis, however, the tube will be under the effect of axial compression and the procedure will continue until obtaining the last load.
I am not able to make this interconnection between the analyses. Any tips?
I have already try many ways, but didn´t worked.
