Dears,

+YROD in Caesar-II works just like YROD in ver 5.00 - why ?

Should it not work like +Y ?

regards,

They are both the same thing. A YROD is a swinging restraint, from a pivot point - it can't lift-off.

Sir,

Thanks for the clarification.

But, isn't it proper to drop +/-XROD, +/-YROD & +/-ZROD in next revision if they are same as XROD, YROD, ZROD respectively to avoid confusion ?

I understand your simulation logic of 'swinging restraint, from a pivot point - it can't lift-off'; but is it realistic ?

With the type of upper & lower attachments of rod hanger, it is difficult to think to load the rod hanger in compression where it will work like a rigid strut in your simulation at such a low cost of support hardware.

Yes you're right.

Just like a Y restraint defines an X-Z plane of free motion, the sign on these rods point to the center of the sphere of free motion (the length is teh radius of this sphere). A +YROD will show Y displacement greater than or equal to zero and a -YROD will show Y displacement less than or equal to zero.

If you enter an unsigned rod (e.g. YROD), CAESAR II will convert it to a positive rod (i.e. +YROD) in teh input processor.

Do not confuse CAESAR II input with actual hardware response in the field.
