Re: errors when running solver

Hi,

your mesh has a problem, there are degenerated elements in it.
Try to make a slightly coarser mesh and rerun the simulation.

Re: heat equation

When I look at the pictures, I don't see an obvious problem. Do you? I may be missing something, of course... ;)
Normally I would just not set any BC at the symmetry border. Since there is nothing behind it, there is nothing which can exchange heat with the half pan.

Re: heat equation

Hi,

I don't know what you want to do exactly...?
Maybe chapter 9 of the Solver Manual is interesting for you.

Re: Rayleigh Damping

Hi,

it sould work if you write

Rayleigh damping = Logical true

There is a SOLVER.KEYWORDS file in the lib directory of the Elmer installation. The "Rayleigh damping" keyword is not listed there, so Elmer doesn't know that it is logical.

Re: Tutorial 4 Loaded Elastic Curve

Hi,

go into your Elmer installation directory to share/ElmerGUI. There are directories edf and edf-extra. edf-extra contains xml files for additional solvers. Move those you need to edf, and it should work.

Re: 3D magnetic simulation

Hi,

get the latest binary for Windows here: http://www.nic.funet.fi/pub/sci/physics ... n/windows/ and start it. That's all.

Re: Elmer installation in Lubuntu 18.10 by ''apt-get install''

Hi,

did you try to install elmer-csc-eg (not elmer-csc)?
It seems that at least under Ubuntu 18.04 the installation from ppa works, see here.

@Elmer team: is it possible that binaries for Ubuntu 18.10 are not (yet) configured in the ppa?

Re: Electrostatic potential of a cube of steel

Hi, for a steady state simulation, initial condition makes no sense a priori. However, AFAIK it is used as initial guess for the iteration. For your second question and many others you might have, you should first have a look into the documentation. The most important are the Solver Manual (see chap...

Re: Electrostatic potential of a cube of steel

Hi, you need a boundary condition in order to get a valid result. ElmerPost does still exist, but is no longer supported. Instead ParaView is the recommended postprocessor. To use ElmerPost, you need to change the file extension of the post file in Model->setup to .ep. More generally, to get started...

Re: Exporting gmsh file in ElmerGUI

You can try Salomé which is far stronger in CAD, i.e. generation of geometries. The mesher is different from gmsh, it is a matter of taste.
