Page Layout ⇒ One column inside a twocolumn document class

[Dryas]

Hej everyone !


I am trying to switch form a twocolumn document class to one column, and then back to twocolumn, but without any page break. If possible, the best would be if it could finish the previous text on top of the page, as shown in the attached document.

Of course I thought I could use \twocolumn[{What I would like to be in a single column}], but there is no way I can prevent a page break before it.

I don't want to use multicols, for I have several chapters, and some with many figures and tables (thesis, hej...). So a break between two {multicols}{2} would not do it. Neither {multicols}{1} for it creates one column inside the twocolumn document.

When I use {minipage}{\textwidth}, my text then tramples on the next column. When I use it inside a {figure*}, then it float as I would like to be precisely Here, but if I precise [H] it vanishes. the problem is the same with different box environment.


I am out of ideas and out of internet pages, for this a priori quite simple task
Has someone an idea?

(I really can't understand why this page break is forced... Seems silly, when we could easily add \pagebreak before if desired.)

Those are my best attempts sofar
