Moses Ship Launch Simulation

Hi,

I am currently working on Ship Launch Simulation, I had created Ship Geometry model and Ship Launch model and Prepared .dat file from MOSES Modeller. 

I find most of the manuals and tutorials are referring to Jacket Launch. 

I am trying to connect the two bodies using Assembly lleg command but it seems that It shows the model cannot be displayed.

The two bodies do not connect each other i.e Ship and Launch way. 

1. Does moses can able to launch bodies that is modeled using the Modeller?

2. The Launchway body modelled is actually representing the Launch jetty rather than barge what could be the steps involved. Do I need to change the change the operation design as Barge where I need to change the angle as 4 degree.

3. The Launching is occuring with the force of gravity so no winches will be involved.

4. Do I need to include the structural property of the ship like girders and web girders for all the frames inside the hull. Is structural class is required to create for this analysis?Two Bodies (One Ship hull & LAUNCHWAY)

5. The Tpin command is used to define the parameters at the end of the launching barge. In this scenario, we have launchway that is inclined at 4 degrees as shown in the picture above. Kindly suggest me what would be the best possible location of -tpin. The inclination starts at the first 5 m. Total length of the launchway is 100 m, Total length of the ship is 100 m.

I am stuck with this tried tutorials and manual files, example. 

awaiting for reply,

Thanks
