Hi,
I'm a new comer and I have some problems modeling equipments with CAESAR.
I want to model air coolers and I'm not sure if it is necessary to put Rx(x is coordinate perpendicular to axis of air cooler) or just x,y,z restraint is sufficient?I searched the forum but I couldn't find a clear and reliable answer.
Thanks

Hi timi
You need to model anchor( 3 displacement & 3 rotation) with displacement.
Check your vendor drawing sometimes air cooler is supplied with expansion bellow nozzle connection then things will be more easy.

In addition tube bundle stiffness you will also get from vendor, that is required for better simulation of header box.

I can't say I've ever seen expansion joints used on fin fan/air cooler nozzles. I've also never gotten a stiffness value for a tube bundle.
