Hello all,
I want to know which directional restraints should i put to get the rigid support( allowing atleast one directional stiffness)

Thanks,
Jacky

All restraint types are rigid in the opposite direction specified, until you input a stiffness value.

E.G. A +Y is rigid and prevents translation in the -Y direction.

In CAESAR, a "rigid" support is 1x10^12 lbf/in, which is roughly the weight of one hundred Pyramids of Giza.
