Dual Rigid Diaphragms in Same Floor

Post by Eigen »

Dear All,

I wish to know is there an option in OS to create a floor slab with more than on rigid diaphragm which is not adjacent to each other? I want to know the relevant code part of it in the OS source code. I wish to know also the literature alternative, if there is any, which one OS implements and any entry point to find them?

I did a google search for that but it seems that it didn't retrieve anything useful?

Your help will be appreciated,

Regards,
fmk

you can just have 2 master nodes and cosnstrain the slave nodes to a master node .. you cannot have any duplicate nodes between the 2. (doesn't make sense if you do and you will get garbage in the output).

the code for the RigidDisphragm just constructs a series of MP_Constraints. How the constraints are enforced depends on the constraint handler (Penalty or Transformation)
