It worked for me

[rjsa]

Duhhh. That did it, tks.

I got almost doubled Cl and Cd with the same car. Is there somethig wrong with the new version?

[LVDH]

I hope not, I did not change anything related to solving.

Thanks for the update! I get so many useful informations from the new feature. I also like the numbers about the contribution of each component to front and rear df.

[Ft5fTL]

The aditional stuff on the solver is very helping, so does the new streamlines but as i said i got some wrong numbers. There is no way i could get 1.57 cd and 7 cl on a low drag setup.

In the "solver.log" file I see the correct values (many groups of measures, one for each component). I did not complete the simulation yet, so I can't say anything about the html report.

[LVDH]

Please someone confirm that you get the exact same values as before. Nothing should have changed. We need to make sure that Ft5fTL is making some kind of user error.

[CAEdevice]

I will check the html report tomorrow, but the solver.log is ok.

A question about the new feature: if I need to measure the df of a partial volume of the car body, do I have to split the body into two parts (and put them in the same folder)?

[LVDH]

Right now every part in the vehicle_body and the high_res folders are measured separately. So if your body consists of a cockpit, a floor and fenders you could just put them as separate body into the vehicle body folder and you will see the forces for all of these parts instead of a combined body force.

Ok, for now I have just separated the mirrors for a test.

Looks like its an post processing issue. Everything seems normal on the solver.log.

[rjsa]

I have a request: Can on the next release the full force coefs be written last on the log? So that we can have them readable on screen between interactions during calculations?

[CAEdevice]

I have just checked the results of an old simulation repeated with the latest WFlow pre processor: everything is ok (HTML report included).
The only issue is that there is no data about the heat exchangers flow (but it is written in solver.log and the value is correct).

[Ft5fTL]

I have no idea what the issue was but it's fixed now. I should have test at least twice before writing.
