Elmer Discussion Forum

Hi,

I used GMSH to create a Mesh and imported it via command line into Elmer.
I was able to do the steady state heat simulation and now I want to view the data.
I can see the colour on all the surfaces of the object, but I want to know how the heat is distributed inside the object.
Do I need to do 3D meshing for this? How I can cut out a slice of the object so that I can see the temperature distribution inside the object,

thank you

Hi

Look at:

Thank you

Thanks. I have another question though.

I have managed to show the temperature distribution inside my geometry.
But now I want to be able to find out the temperature at a specific point inside the geometry.
I want to be able to plot the temperature distribution along a specific curve which I define.
How can this be done?

thanking you

Hi,

I would advise you to write tvk output and use ParaView for postprocessing. There you have the "plot selection over time" and the "plot over line" filters, and many more. It might also be possible to do what you want using the SaveData/SaveLine solvers, but I am not sure - you can have a look into the Models Manual for more information.

HTH,

Hi Matthias!

Thanks for the quick reply.
Do you mean tvk or vtk output?
Could you please refer me to a manual about how to write output?

thanks
VVS

Hi,

I made a typo, it was vtk of course. In fact, it's rather vtu which is a variant of vtk.
To write vtu output, either you say
in the simulation section, or you use the ResultOutputSolver, see ModelsManual.

HTH,

Hey!
Thanks for the hint Matthias!

but where exactly do I write Output File = "myfile.vtu"?

thanks
VVS

Hi,

my hint was not entirely correct, sorry. See the correct answer here.

HTH,

Matthias
