Boundary Condition in a co-simulation
 

Hi,

I am running a co-simulation with Abaqus in a implicit coupling. The case is a free-falling lifeboat starting 20 cm before the water surface with inital conditions of 60 degrees and 21 m/s velocity. I have established a co-simulation and it is running, the problem is that the pressure from Abaqus odb is not the same, or has the same tendency, as the pressure obtained directly from Star. Since this is a moving body, should the Abaqus model have any boundary conditions? The user guide for Star only states that the models should be equal, which they are, at least in size, weight and moments of inertias.

Thank you for all replies.
