Defining COG Point

Hi,

I have a ship model with COG coordinates and total displacement given to me with fully loaded condition.

But in my model, I am not modelling each details. So I think I can achieve the total displacement of ship by adding admas to it.

But my query:

1. How can I locate my COG point of whole model once all the setup is done. (I guess COG will not match with the given data as not modelling with minute details)

2. How can I change the COG point if it is not matching with the provided data. (Model is flexible, no rigid parts to be model).

3. How can I visualise the COG point before or after modification of coordinates.

Thanking You.

Go to post>summary

Then load the solver profile and the centre of gravity under the same

With this you can view the centre of gravity value of the model or part etc. and compare it with the given data of cg coordinates

Hi,

You can use the Summary module to get the CoG. Goto Post>>Summary>>load the RADIOSS>> CoG script and check the CoG

Isn't that CoG depends on the model? So you may have to tweak the model without adding Rigids
