Hi,
Yes there seems to still be an error in the source code here is a solution you could try:
Adding just one line of code in the file sources/postel3d/lecdon_postel3d.f
Around the line 200
The lines to add are the line 201 and 202.
Hopefully that should solve the problem.
196 IF (I(6).EQ.1) THEN
197 VARSUB=.TRUE.
198 ELSE
199 VARSUB=.FALSE.
200 ENDIF
201 ! Skipping date if present
202 IF (I(10).ne.0) READ(POS_FILES(POSPRE)%LU)
If this still does not solve your problem could you send me your file so that i can test that.
Hope it helps.
