Swapna Barman figured among the bottom heap in the seven-event heptathlon on the second day of competitions.
Dutee, who got a quota entry despite failing to come up with the qualification standard, finished sixth in heat number five of the women's 100m first round after clocking a below- par 12.07secs.
The Odisha girl's performance was well below her season's best of 11.30 seconds though the track was a bit damp after light rain lashed the Olympic Stadium during the women's 100m first round and the temperature also dropped below 20 degree Celsius.
It was always going to be tough for the 21-year-old Dutee against a top class field in this global event. There was an outside chance of making it to the semifinals and her performance would disappoint all those who have been racking her career.

Dutee, who ran at lane number six, said she got nervous due to the disqualification of German athlete Tatjana Pinto, who was at the adjacent lane number five, for a false start. The Indian also had a slow start as her reaction time was 0.174 secs, the sixth worse among the seven competitors.
Dutee did not touch the qualifying standard of 11.26 secs during the qualification period but later got a quota entry on the basis of her season's best of 11.30 secs as the total number of participants in the women's 100m dash did not reach the targeted 56 in that event.
Gina Luckenkemper of Germany topped the field leading into the semifinals with 10.95 seconds while Marie-Josee Talou and Murielle Ahoure, both from Ivory Cost, followed with 11.00 secs and 11.04 secs respectively. Reigning Olympic champion Elaine Thompson of Jamaica also went into the semifinals in fifth place with a timing of 11.05 secs.
In the men's 400m first round, Anas' was at the final heat (number six), and he needed either to be in the top three or run better than 45.70 secs to qualify for the semifinals. The 22-year-old Kerala athlete ran a season's and personal best of 45.32 secs in mid May in New Delhi but he could not replicate that feat here, clocking 45.98 secs to finish fourth in his heat. Overall, Anas finished 33rd among the 52 competitors.
Anas came out of the blocks in good time of 0.155 seconds, the third best among the seven competitors, but lagged behind the others after the first 100m.
"I am disappointed. Now I hope to do well in the Commonwealth and Asian Games next year," he added.
Botswana's medal contender Isaac Makwala was leading the semifinal qualifiers with a time of 44.55 seconds while reigning Olympic champion Wayde van Niekerk of South Africa won his heat with the 16the best time of the first round, leading into the semifinals.
Barman, who has a season's and personal best of 1.87m which she achieved while winning gold in the Asian Championships in Bhubaneswar, could only clear 1.71m. She collected 959 points from the 100m hurdles and another 867 from high jump for a total of 182 points to be at 27th spot after two events.
