The lowest element of a member must not cross the free surface

[Ry8icks]

Bug description The error : "The lowest element of a member must not cross the free surface. This is true for MemberID .. ' is issued.

To Reproduce This is for a member crossing the free water surface. However I've gotten rid of the error message by rewriting the code slightly (Morison.f90).

The new code looks like:

! ! Correction next line. B. Melhus, 29.09.2021 ! else if (0.0 > Zb) then else if (0.0 >= Zb) then ! fully submerged elements.
! NOTE: For an element which is fractionaly in the seabed, the entire element volume is added to totals member%Vinner = member%Vinner + Vinner_l + Vinner_u member%Vouter = member%Vouter + Vouter_l + Vouter_u member%Vsubmerged = member%Vsubmerged + Vouter_l + Vouter_u ! ! Correction next line. B. Melhus, 29.09.2021 ! else if ((0.0 > Za) .AND. (0.0 <= Zb)) then else if ((0.0 > Za) .AND. (0.0 < Zb)) then if (i == 1) then call SetErrStat(ErrID_Fatal, 'The lowest element of a member must not cross the free surface. This is true for MemberID '//trim(num2lstr(member%MemberID)), errStat, errMsg, 'SetMemberProperties') end if

and the error message is not issued. The error was issued because Zb=0 (i.e. exactly equal zero). Having rewritten to 0<Zb will make it work.
