Relax Guys, Relax
I read your experiences and suggestions about problems, warnings and many things about robot.
Unfornately i must say that almost of them are NOT true.
I read something about instability types, errors on rigid diaphragms, and many many things, and i must sa that instabilityes are not errors of program but are modeling mistakes and staticly instabilyties at structures given by user, ( you can reed manual of robot for instability types 1,2,3 ....and reasons why)
For rigid diaphragms you must define yourself propertyes of rigid diaphragms ( not by library) and be carefully when you restraint all directions, because if you want to define inplane rigid behaviour you must restrain X and Y direction of moving compatiblity, and not Z.
I agree with you that there are many good softwares for structural analysis purpose ( like SAp, ETABS, Midas GEN or CIVIL, ......) and i agree to you that CSi is very great ( otherway with some weak points) , but also ROBOT is good for many structural analysis purpose, especially for low and middle rise RC and steel buildings.
Relax, And maybe we can discus for any point step by step
Good Work
