Save initial condition for movie

[paugier]

I tried snek5000/snek5000#142 (comment)

but I get a strange compilation error:

   95 |       else if (istep .eq. 0 .and. (.not. chpt_ifrst)) then
      |                                        1
Error: Operand of .not. operator at (1) is REAL(8)

Could you try adding implicit none (just before the include statements inside userchk) so we know it is not implicitly set as real.

Yes that was the problem. With implicit none, I get a much better error message. And no error when CHKPOINTD is included.
