simulation of C-section with gusset...

Devi Prasad Samal Sep 19, 2010 5:14 AM

Hi,

I am doing a simulation of C-section beam. when we go for simulation we have beam element. but in my structure there are some gussets are placed in between the c-section for additional strength. hence when i go for the analysis or meshing.the gussets are not properly connected. as they are treated as solid mesh.

so what should i do to solve the simulation?

i have thinking about taking the wholemodel in solid but it's giving some different result comparision to beam mesh and it's also not possible to go for larger structure.

please suggest a method, how can i go for a analysis of C-beam containing gussets?

Treat all objects as a Solid. This change has no impact on simulation

  but it takes a lot of time to find out the result. As my assembly consist of many number of structures and every structure contains min 3 number of gusset in between them. now you can imagine how much time it will take to solve the problem.
  
  so my question is if there is a gusset in the beam then is there any method through which we can use beam mesh?
  
  by the way thanks tomasz for the reply...
  
  if i can't found any other method then my last option is to go for the solid mesh....
  
  bye...

    Hi Devi,
    
    I think treating all bodies as solids is probably your best bet in this case. You can create contacts between your solid body gussets and the c-section beams but I am pretty sure that they would not work since there would be a small amount of contact area. Have you tired using Mesh Controls to vary the mesh for your solid body study? By doing this you can usually make a coarser global mesh and then just refine the mesh in the areas that you need to in order to get the model to mesh properly. This may decrease the solution time. Just a thought.

      Hi ryan,
      
      thanks for your suggestion. i have work on the things already which you told. i am actually looking forward a solution for beams. but i think it is not possible for right now.
      
      by the way thanks for the help...
