Parabolic Boundary condition

Please login with a confirmed email address before reporting spam

Hi,

I have a question concerning the BC in the structural mechanics module. Under Prescribed Displacement one can choose for General Notaion, and one gets the Hu=R matrix setting. If you want to have a paraolic BC, thus u^2=v, then one has to work out the matrix accordingly and implement this in H.

The solver generates a warning:
New constraint force nodes detected: these are not stored !

What is happening here?



Regards,

Helger
