I am trying to determine the hydrodynamic coefficients of a two body WEC using multi body dynamics in AQWA. However, when I am trying to run the simulation, I am getting an error, "ILLEGAL CONNECTIVITY. Element 1 is joined to element x and element y".
Initially I did not leave any gap between the two bodies. After going through some sites, I read somewhere that ANSYS AQWA is not able to recognize contacts and a little gap is to be left. But even after adding a gap between the two bodies I am getting the same error.
