I have an urgent question right now,
I do have access to a trail licence for my research, however I could not setup the licence server, hence me using the educational version on my laptop.
I forgot about the 100k node limit, and basicaly have left my laptop meshing for 7 days on a ship hull. Now the student licence has the Radios Program build in,
Is it at all possible to run the radios simulation without saving in the student licence? or did I thanks to my mistake just lose 7 days?
Seccond question:
First I wil go into the background of the casus
I am doing my graduate research as Student Naval Architecture for the Dutch Coastguard. I am looking into the effect or risk the current and upcomming wind turbine farms on the North Sea create regarding Ships 'Not Under Command', which means they either lost propulsion or steering or both, which means they are drifting where the wind and tidal current brings them. Next to risk areas and the impact analysis I also look at how to lower the risks, and placement of one or multiple emergency towing vessels.
Within Hyperworks, and as I have been adviced by some of the people from Altair, I am prepping for Radioss,
Basically I have 20 meter long halfcut sections of different ships, next to that I have a wind turbine foundation as commonly used on the north sea,
Both objects have been made midsurface meshes off, the foundation took 7 days to mesh, one of the bigger shiphulls with 18 days continuous is still meshing.
Both objects will get basic steel properties E=210000 and poison of 0,26
The shiphulls will get a mass equall to the mass of the entire loaded ship, though as of this moment I am not sure whether to apply this mass as force or list is as mass of the unit.
The turbine foundation will be clamped solid at the seabottom instead of beeing clamped in with dampened springs (soil) to make the calculation simpeler.
The drag and other water effects are neglected for simplification
Both objects have to deform and desirably the shiphull will have to tear.
Desired outcome:
The basic point of the above is to figure out at what speed at the point of impact the shiphull will tear,
As far as I have understood it now I will have to run the simulation multiple times to figure out at what speed this will occur.
Why:
When the shiphull tears the cargo contents will spill or worse, the ship will sink.
This will lead to an environmental disaster, that can be calculated back to environmental damage and human casualties based on existing examples in the past.
I have real data of drifting speeds over the past 5 years, I will be able to compare the speed with real life data, and then can narrow down if a ship basicaly drifting by wind and tidal current can split open by colliding with a windmill and at what wind speed, in beafort, that will likely occur.
The questions sumerised:
Hyperworks student edition:
- Is it at all possible to run the radios simulation without saving in the student licence? Or did I thanks to my mistake just lose 7 days?
Hyperworks 2017 Trail:
- The shiphulls will get a mass equall to the mass of the entire loaded ship, though as of this moment I am not sure whether to apply this mass as force or list is as mass of the unit. How woud you advise to apply this mass
- As far as I have understood it now I will have to run the simulation multiple times to figure out at what speed this will occur. Is there another method?
Thank you very much,
A J Prins
