Welding simulation cfd
Hello.I would like to perform a welding simulation that will most faithfully reproduce the TIG welding of pipe and elbow or to be more precise perform simulations of undercut weld defects.
Is it possible to perform a simulation showing the undercut defect in Ansys Fluent or OpenFoam? Pipe has diameter DN 400 length 1500 mm Elbo also has diameter DN400 (2D wg EN 10253-1: 1999). The total volume of elbow and pipe is 16451397 mm^3 . Mesh size lenght I assume 0,5 mm volume of one element is 0,5^3 = 0,125 so if I divide 16451397 by 0,125 I get 131 611 176 elements. Is this a good approximation of the number of elements? I I did not take into account the additional number of finite elements for the binder. |

As for the mesh size, the number of elements you've calculated seems to be a good approximation based on the assumptions you've made. However, it's important to also consider the additional number of finite elements for the binder to ensure an accurate representation of the physical behavior of the welded structure. |
