The factor is to correct the youth modulus unit and therefore should be at the youth modulus in my opinion.shoogen wrote: An where does the factor 1000 originate? ...
OK guys may be step by step ...
The following branch has changes to get correct results using the FemWB
fix1 - load direction
fix2 - adaption of youth modulus unit is made at youth modulus and no longer at the load
fix3 - material cards of steel and concret to work with fem

attached an example file for testing (you may have to click on FemConstraintForce first to correct the direction, the original problem of this thread see first post) EDIT: CalculiX example http://web.mit.edu/calculix_v2.7/Calcul ... node7.html
FemWB f = 0.0879 m
BeamFormula f = 0.0877 m
CalculiX orginal file from manual f = 0.0877 m
with the applied patch and this real workl example it is may be easier to talk about the load unit stuff ...
