anant,

Finally realized that the output was in ver 5.1 to be able to view it.

The very high restraint loads are actually occurring in the operating case 8 and 9 with large RX loads at node 122 ( from U1 where GX=1.0 ?) The guide restraint gaps are not closed in the thermal expansion cases.

Could you please explain the reason for GX=1.0 , GY=1.0 , GZ= 1.0 uniform loads? If these are for seismic loads, then I think you might need to revise the guide restraint gaps to the thermal displacement values (smaller - not larger gaps). I did not review all the 33 cases.
