Full Forcing Manager

Hi there,

I have a question about the import of csv files.
I uploaded weather dates from this year, but the table under the heading "Forcing File data content for each day of the year" shows this data for the year 2018. So when I wanted to start the simulation with june 2020 it's not possible because the data for the year 2018 was saved. In the csv file it's the right date.

What can I do?

Kind regards, Lavinia

Hi Lavinia,

It is a Forcing Manager convention that the base year is automatically set to 2018, as e.g. EPW or TRY files do not contain a year and the base year has to be set. The year though has no influence on your simulation, the results do not depend on the year but on the input data you define in the CSV file. And as that does not get changed, there is no difference. So you can simply run your simulation with the date in June 2018.

With that being said, you could theoretically manually change the year in the forcing file so the correct year gets displayed, however, we do not recommend manually editing our files as this may lead to corrupted files and thus problems with the simulation.

Best,
Laura

Good morning Laura,

thank you for your helpful respond.

In this context a termination of the simulation occurred. When I read in the EWP file, the simulation did not start at all. I then created a csv document with the data for the day I want to simulate.
Here my first question, is this sufficient or do I have to load a certain minimum amount of data (e.g. one month)?
And second, I would like to know how to proceed if the simulation is aborted during the simulation or at the beginning because of unstable turbulences.
So far I have worked without nesting grids, are they necessary?

Kind regards, Lavinia

Dear Lavinia,

It is sufficient if you only have "real" data on the dates that you would like to simulate. When loading the forcing file in the ENVIguide, it will tell you if that is the case.
It depends on what the reason for the crash is. It always makes sense to have a look at the Model Inspector in Spaces (Tools Tab) and see if your distance to the top model border is high enough. You can always have a look at the output files (panic dump) to see where the problem may occur. We do not recommend using nesting grids, if you think that your buildings are too close to the model border you could simply remove some grids of building or add some normal cells around the model area.

Best,
Laura
