      Semiimplicit command can overwrite other commands. The following commands are affected: 1.Nsub and deltim: During the explicit solve phase, the time incrementation does not follow the nsub and deltim commands 2.Etcon: If semiimplicit command is issued, etcon command is ignored. 3.Outres: During the explicit solve phase, the results files writing frequency specified in outres command is ignored unless a negative number is specified. 4.rescontrol: During the explicit solve phase, the results files writing frequency specified in outres command is ignored unless a negative number is specified.
