A simulation condition input apparatus inputs information required for
simulation analysis on a system including plural element members. The
apparatus includes a display unit, a specifying unit and an input unit.
The display unit displays the plural element members on a screen with
geometrical shapes corresponding to the element members. The specifying
unit specifies a contact portion between at least one set of the element
members, which is an information input target, on the screen of the
display unit. The input unit displays a new window screen and inputs
information about a contact state of the contact portion specified by the
specifying unit.
