how can i perform finite element analysis on a ship hull in solidworks

By Taufiqul Islam on 14 May 18:38 6 answers 3 comments

I have a ship hul in igs format. i need to perform FEA for strength analysis of that hull. cant find any tutorial about it. i would be glad if someone would be kind enough to show me the way or at least link for learning the way.

    Hi Taufiqul,

    Typically in both inventor and solidworks, an FEA can't be performed on an iges file. What you need to do first is open the iges file and then save it as a sldprt file or sldasm file. Then you should be able to perform the FEA.

    I just opened your file. There is a large opening near the back. I will patch this up for you and send you an ipt file of this for you. That can be opened in solidworks. How thick is your hull suposed to be? The hull is literally a paper thin surface and has no mass so an FEA would be impossible in its current state. Let me know this and then you should be able to perform the FEA.

    I just noticed the ship hull you have created when I was doing repair is over 300ft long. Is this by chance a surface model of a military type vessel? If so, the hull would be almost a few feet thick in parts.

    Taufiqul Islam,

    Here is a step file of the ship hull all patched up. The hull is now 3 inches thick which is the thickest I could make it. I also posted the fixed model to my page on here and referenced you. Let me know if this model works for you.

    Yes bro the hull is the surface model of a frigate. As I have not yet completed with my load calculation that's why the thickness is not yet confirmed.

    And again thanks for taking so much pain and correcting my model. Saying thanks would not be enough. This is part of the project that I have to complete by October. For Military threat analysis calculation I have to perform fea on my model but whenever I imported the file to solidworks the surfaces didn't patched up. However I ll let u know aboit the model nd will b knocking u for further advice. U R great. :-)
