material and fem: main material cards work with fem

[bernd]

As Jürgen proposed here: viewtopic.php?f=18&t=7172&start=30#p70061

... That means also the Material DB. There we need to add a Unit to all constances...

Started to do that. Added units to the youngs modulus of main material cards and added generic wood material card.

@Yorik
You added dozens of material cards 3 month ago. Where do they came from? They all have youngs modulus unit N/mm2 = MPa. FemWB will them track as kPa since the unit is not written behind the number at the card.

Merged.

A user made all these cards... Indeed we should add units to them. Maybe there is a way to do that automatically...

They where posted here: viewtopic.php?f=8&t=8800#p72522
The user posted first a list with units.

Doh... I guess the units were not supported at that time. Anyway, I just found a way to add the missing unit automatically.

Hello,

is the Problem with the units solved? I have created all these cards, and i thought that FreeCAD works with mm, so i write these constances in N and mm.



Kind regards

Yes see Yoriks commit. https://github.com/FreeCAD/FreeCAD_sf_m ... ed5664f012

Thanks Yorik for fixing it that fast. Fem is making a little progress ...

Thanks for all the cards. Yes internally FreeCAD works with mm but since a unit system was implemented FreeCAD accepts lots of different units. units and all supported units: https://raw.githubusercontent.com/FreeC ... tyParser.l
