hi to everyone, I am new in the forum: I press that I have not found the section in which you present so I do it here too (if someone can tell me thanks!)
My name is Marco I am 26 years old and study ingenuity mechanics, I am doing the thesis for the master, and for the first time I use hypermesh. the work consists in the resolution of an omega section profile, to which a load in half-works (wins at the extremes) is applied for bending and a pair in one end and the other bound.
the problem arises when I go to create the two load subcases(loadstep): to apply the bending I used a rbe2 on the cross knots in half-works, which unfortunately during the torsion gives me a stiffness to the profile, which should not be there!
any advice on how can I avoid this stiffness given by loading? I tried to use rbe3, stiffness disappears but the applied load is not through rigid element so I can not solve it so ́.
the solutore used is optistruct. I read that you could use the mpc function but I did not succeed
Please help!
I apologize for some typing error but I have a foreign keyboard!
