Time averaged fields on a defined time range -- CFD Online Discussion Forums
When I re-run a part of my simulation with this function enabled, it works well. In the "case/timeStep/uniform/fieldAveragingProperties" file, the "totalTime" corresponds to the time from the start of the function and it grows accordingly to time steps which is totally logical. The averaged fields seem ok too.

Interview with Emmanuel Macron: 'We Need to Develop Political Heroism' - SPIEGEL ONLINE - International

Nothing here should become habitual, because routine lends one a deceptive feeling of security. You begin not noticing certain things and lose your focus on what's important. Uncertainty and change keep you attentive.

It is a place laden with history. The emperors spent time here, Napoleon I and Napoleon III. In the Fourth Republic, it was the palace of a president without powers. Only in the Fifth Republic did Charles de Gaulle move back in.

Germany is different from France. You are more Protestant, which results in a significant difference. Through the church, through Catholicism, French society was structured vertically, from top to bottom. I am convinced that it has remained so until today.

France is a country of regicidal monarchists. It is a paradox: The French want to elect a king, but they would like to be able to overthrow him whenever they want.

I am a strong believer that modern political life must rediscover a sense for symbolism. We need to develop a kind of political heroism. I don't mean that I want to play the hero. But we need to be amenable once again to creating grand narratives. If you like, post-modernism was the worst thing that could have happened to our democracy. The idea that you have to deconstruct and destroy all grand narratives is not a good one. Since then, trust has evaporated in everything and everyone.

I am putting an end to the cronyism between politics and the media. For a president, constantly speaking to journalists, constantly being surrounded by journalists, has nothing to do with closeness to the people. A president should keep the media at arm's length.
