Elmer cannot help you here.

Hi, Does anyone know how ELmer treats discontinuities in Dirichlet boundary conditions at corners? The best example I can give is the lid driven cavity problem, where in a square domain, the left, right and bottom boundary has u = 0, while at the top boundary, u=1. This will create discontinuities a...

Hi Annier, The problem is not about the inversion, but the overlapping of mesh due to the updates. I was expecting Elmer to fail to solve or throw up some warning or error messages but it didn't. I am not sure how reliable the solutions are but if the overlapping of mesh isn't an issue, I guess the ...

That doesn't seem to have any noticeable effect on the bubble. The only parameter that is important seems to be $equilcons = 0.9, i.e. the value controlling the equilibrium concentration of the bubble. As the bubble grows beyond a certain size, the mesh gets inverted inwards.

Sorry, it wasn't the initial condition but something is not allowing Elmer to run. I am getting error called Fortran runtime error: Bad real number in item 1 of list input. Perhaps this has something to do with the model, Anil, once you get the latest version of Elmer working, do give it a run and s...

I think the initial value of Air is zero, so there is a 1/0 statement and Elmer doesn;t run after that. So, I tried playing around the values of constant Young modulus but I cannot seem to observe any significant effects. I am just puzzled that Elmer does not throw in a warning or error message when...

Yup, it is exactly that point that causes it to be inverted. The normal is in the opposite direction. It seems to work now although I am curious about how Elmer interprets the mesh when they have zero volume or overlap. As you can see from the figure Zoom, the mesh at the bubble boundary seems to ov...

Hello Peter, The results are shown here for t = 1 and t = 49. I also show the plot for mesh update at t = 1. Now the diffusion and the mesh update seems fine but I think numerical error for the calculation of the flux causes the mesh to be inverted inside (see meshupdate plot). Is it possible this i...

Hi,
This is the result that I get after t = 4 and t = 49. The mesh seems to get inverted inside. Bear in mind that I am just running the sif file as it is using the mesh uploaded from the post on 12 Jan. Are you expecting something like that, which seems unlikely?

Hi Anil,
I will run it over the weekend and let you know of my results.
