GSoC2020, FEM: extend examples

[bernd]

In which regard, only the warning with ConstantVaccumPermittivity is left.

If the results are fine than go for the tests (it would mean the obj is not ignered). I will have a look at these warning.

Tests for elmer examples, including thermomech bimetall: https://github.com/Sudhanshu-Dubey14/Fr ... d7fcc617c2
They are all in standard FreeCAD units. Should I also make in SI units?
And they all pass on my system.

Did you double check the results with calculix and the calculation from the paper in the bimetall topic.

The displacements results are as follow:

Magnitude:
calculix: min= 0, max= 7.15
elmer: min= 0, max= 7.23
uz_max (manual): 7.05

X:
calculix: min= -0.034 , max= 0.25
elmer: min= -0.035, max= 0.25

Y:
calculix: min= -0.006, max= 0.006
elmer: min= -0.006, max= 0.006

Z:
calculix: min= -0.001, max= 7.15
elmer: min= 0, max= 7.29

All in FreeCAD standard units
So yeah, the results are all pretty close.
The temperature shown by elmer is 373K and I think I did saw 100 deg C in the manual calculation, though I am not sure if that was a given value or a result.

Anyway, the displacement results match approximately so it should be good to go.

BTW: There is a side work you could help with, if either HoWil or me are to slow in control the examples. https://forum.freecadweb.org/viewtopic. ... 10#p418922

since we had to change the mesh type of all examples to gmsh mesh to be able to remesh all examples and with the new elmer examples we started to really improve the elmer solver, this is even related to GSoC somehow. Means it could even be mentioned there as part of your work.

Sure!
By the way its 30th already, so just a reminder to finish the evaluation if you haven't done it already.

[HoWil]

Please do not forget to finish the second evaluation. It is open from today till the 31st of July!

Done with my part.

ping

Will you do the evaluation also this time?

[bernd]

done

Are you directly running the example, or setting it up and then solving it.
Cause the warning comes when you write the input file using GUI after setting up the example.

I am still getting the warning.
