EFM clarification

[Ekoj]

Hello guys, I'm currently working on a educational EFM (mainly to understand how DCS communicate with my c++ code) and so far, things are going well. I've seen in a Razbam's harrier video somewhere on youtube some green lines comming out of the plane, whose I think are the forces vectors representation for debuging purpose.

 

Only function I see in the EFM API which would do that trick seems to be : ed_fm_enable_debug_info();

 

Also after analyzing Cpt Smiley F16 educational code, I found quite strange to not use any of the add_global_force or add_global_moment, only local force, which are applyied to the center of gravity. I'm not a huge fan of lift beeing applyied to the CG, since it's should be applyied to the center of pressure which is differrent. Well anyway that's another story.

 

If you have any information about the use of ed_fm_enable_debug_info() and the difference between local and global forces, this would be of a great help!

 

Thanks in advance!

 

Ekoj.

Creating a clickable cockpit will require minimal scripting programming skills, and C ++ programming skills will be required to add an external flight model (EFM).

ed_fm_enable_debug_info()  Command is use for enable additional information like force vector visualization, etc.

 

Local force includes both tangential and radial forces distributed on the stator bore, while global force refers to cogging torque and torque ripple. First, the expressions of local tensional and radial forces are generated based on the specific duration of the magnetic field.

You can try this approach if F16FM's one is not for you, it's still in very earlier DEV.

even : AH6 one

 

If you are an AEROMAN (solid aerodynamic knowledge ) you can build your's, a basic example in API folder gives what you need for, with good data, you can go far with FM simulation.

 

Best regards.

Thanks a lot, both of you!

 

Does anyone knows how to use ed_fm_debug_watch ?

Implemented it correctly in the API header, but can't get anything showing on the top left corner DCS window info screen (Ctrl + Pause)... Is there anything i'm missing?
