GTA (or TIG) Welding Heat transfer and Fluid flow

Post by sebastien ROUQUETTE » 25 Feb 2013, 20:49

Hi everyone,
here is an evolution of the GTAW heat transfer. I considered the Fluid flow. I define the domain 1 as fluid with a high viscosity when the temperature is below the solidus temperature for Stainless Steel 304 and a normal viscosity when the temperature is beyond.
Temperature surface tension, Buoyancy and arc drag force are defined in the boundary conditions (volume force for boussinesq/buoyancy).
All the file are compressed (mesh, nodes, boundary, SIF ...)
Cheers

Hi Sebastien, I have a question, where did you run the model? under linux or windows elmer's program? I run on windows version but a have a problem with "myweldinglibrary.f90" file .... here the log solver

Any idea? i don't usually use fortran with elmer so i'm not sure how it works. Sorry for my english, thank you very much.

Hi,

you need to put myweldinglibrary2.dll somewhere where Elmer finds it, either in share\elmersolver\lib in the Elmer installation directory, or in the directory where the sif file resides.

HTH,

Matthias
