The 23-year-old bean-pole seamer conceded 94 runs in 9.4 overs at Eden Garden in Kolkata on Sunday after being put to the sword by the home side's batters in front of a capacity crowd of more than 68 000.
Jansen has been a top performer at the global tournament, helping the Proteas reach the last four of the competition with a game to spare.
He is the second-highest wicket-taker at the World Cup so far and also the most successful bowler in the opening power play, taking 12 scalps in that period.
Simons revealed that the left-arm paceman was fairly "calm" when he did the post-match analysis with the bowling group after the mammoth 243-run defeat
"The sense I got from him (Jansen) was that he went away from concentrating on himself to concentrating on the opposition, which happens in pressure moments, when you are up against the quality of batter we were playing against," said Simons.
"I said to the bowling group which I think frustrated them that I was hoping we'd have some tough situations. It was a great learning experience for Marco individually but also for us as a group.
"He is pretty calm about it. His answer to the question made complete sense: when you get out of your bubble and start worrying about what's on the other side of the pitch and not what you are doing on your side, that can create [pressure].
"The noise at a place like that can add to it. He is a young cricketer, he is new to the game and these moments will happen."
The Proteas will want to put in a solid performance against Afghanistan before they turn their attention to the semi-final clash against Australia next week.
