highlevel project principle

Hello,

I am planning a modern analysis of the collapse of cooling towers at Ferrybridge, UK 1965.

The towers were thin shells of hyperbolic revolution, subject to gravity load and wind loading.

I would like to model the tower under the dead load and wind loading. I have wind tunnel data collected at the time of the collapse, however, would potentially model the wind flow around the site structures also.

Am I correct in thinking the work flow for this analysis would be similar to below:

Model geometry

      towers + surrounding buildings

Mesh geometry

      towers + surrounding buildings

simulate wind flow (code_saturne?)

export wind loading parameters to salome/code_aster

perform analysis

interpret results

Is this is something along the lines of what is required? Many thanks for any advise, as said I am only looking at the viability of the analysis at a high level at present... the intention would be to write a paper comparing the results of this case with the membrane theory investigation carried out at the time...

Many thanks,

Regards,

Kev

hello

your workflow seems ok to me

however there can a lot of different things in this simple sentence

'perform analysis'

with Code_Aster you have a handful of choices regarding this step

as with other FE codes

however the learning curves> of Code_Aster is rather steep and i suggest getting some practice with simple examples

i would be interested in the paper you are quoting

Many Thanks for the reply...

I intend working through the code_aster tutorials to a get a feel for the analysis and work up to getting the gravity loading on the towers sorted, at this pointy start thinking about the wind loading.

Am I correct in thinking the goal would be:

Geometry ---> mesh (.med) ---> code_saturn ---> .med output (pressure) ---> code_aster ---> .med output (stress) ---> salome post processing

Thanks for the help and help...

I will post the paper when I am finished in your interested...
