Dear all,

when the three {many} displacement is not occur simultaneously. then we have three {many} displacement vectors.

the problem here that the CII make fixation in cell remain empety and this is according to the following note in CII help:

"If an imposed displacement is specified for a specific degree-of-freedom, that degree-of-freedom will be considered restrained for all load cases whether or not they contain that displacement set."

how can forced the system to treat all empety cells as free????????

best regards
