"Basic FSI setup" questions for model creation and post-processing

GPiove
I have some questions about the model creation:
1)     When I create the constraints for the rigid body object and I have to select the application region, I can choose any node without difference?
2)     Why I have to use the function mesh generator? How can I know the number of elements in each direction or the size?
3)     Is possible to create the euler materials without the init cond euler (shape and initial value) but creating a solid and then apply to it the property of the eulerian solid? If yes, there is any difference in the 2 approaches?
Once I created the model and compute the results using Dytran is possible to post process the results with Patran? Because I try to do so but it seems like the cube doesn’t interact with the water surface and the only output that I obtain is the displacement… I’m also interested in the plot of the pressure generated by the crashing.

    1) Yes that node can be anywhere - it is just for displaying the DOFs defined for the rigid body
    2) This is the easiest approach that allows for fast editing and readjustment without meshing a large number of solid elements that would also slow Patran down. I'm not sure I understand the second part - in the Input Definition you define the box size and number of elements in each direction to give you the element size you are using.
    3) This is the old way of doing and makes it a hassle to edit and select elements for non-simple cases, so we recommend only the new approach
     
    Yes you can post process results in Patran. It is best to create a new database to read in model and results - you would need to bring in each result file set.
