Re: [Flightgear-devel] scripted compile from source... results in run_fgrun buttons greyed out, or fgfs cannot open shared object file
Hello Francesco How are you doing lately? :) Hope all are well with you... With respect to FGRUN in your script, maybe you can consider FGO in your future scripts. I find FGO to be light on system memory and easier to manage. This is just a suggestion and i hope you do not mind... Cheers! :) On Friday 05,August,2011 12:37 AM, Francesco Angelo Brisa wrote: Hi, the script is made to duild both fgrun and fgfs if you give no arguments, unfortunatelly, it is quite easy that something can go wrong (Compilation,data fetching etc...). when this happens, you can end up with an inconsistent fgdata folder that makes the git problems. Further more if data fetching stops before finishing, the script is set to stop, so you don't get fgfs nor fgrun. You have to try again, best to wipe out fgdata folder under installation/fgfs prior to relaunch the script. The problem with the blanck parameters in fgrun are due to the fist launch of it, I don't know yet how to make it work without user interaction. If you have problems with fgrun, just launch fgfs only first (sh run_fgfs.sh) and see if it works or not.

Re: [Flightgear-devel] YASIM Issues- Contact Points / Tail Strike
Thank you Adrian, You have much cleared my doubts in YASIM with regards to contact point issues. As for Gears sinking into the ground, even adding a fake gear was not much of a help. Later i got reply from Andres and he was mentioning the origin offset could be the cause and he seems right on that. I will be replying him on that soon, please look out for that reply. Once again, thank you for your valuable input Much appreciated Txs On Monday 27,June,2011 08:56 PM, Adrian Musceac wrote: On Sunday, June 26, 2011 17:27:06 xsaint wrote: Hello All... I am trying to better understand how YASIM calculates its contacts points Hi there, I'll try to answer, see below: 1) As from my experience, the SIM crashes when some part of the wings comes in contact with a building or ground and it does not crash if other parts of the wings hit the ground of a building.The wing specification is correct in FDM as checked againts the blender script. So how does it deduce the contact points? There might be a difference between regular collision detection provided by the FG engine itself, about which I have no information, and YASim _ground_ collision detection. The latter is implemented as follows: Contact points (internally represented as gear objects but with special properties and hardcoded values for friction) are compiled from the wingtips and the fore and aft tips of the fuselage. These contact points will hold at full compression 10 times the plane's mass. So for a conventional airplane there will be two contact points for the fuselage (nose and tail), the main wing tips, the tips of the horizontal and vertical stabiliser. Any collision detected with these contact points will be treated by YASim as a special case of gear collision and compared to the force mentioned above. 2) Eventhough CG looks like it is in correct place, in YASIM, the plane do sink to the ground before take off. Insufficient lift maybe but the back of the fuselage do sink into the runway. As such, as possibility of implementing tail strikes? It is possible that either the aft end of the fuselage as defined in XML is higher than the lowest part of the model, or that the mass which it has to sustain is larger than the spring compression of the contact point can sustain. You can try to compensate the first issue by placing a fake gear object at the lowest point where the fuselage touches the ground. Much all appreciate all valuable replies and also if you could point me towards any valuable YASIM documents. There is a technical document floating on the web, can't quite remember where but try to google YASim-simnotes.pdf Other than that, your best reference is the source code.

Re: [Flightgear-devel] YASIM Issues- Contact Points / Tail Strike
Hello Anders, Yes you are right, after i moved the offset position, the plane do take off without sinking into the ground. But this give rise to another issue, as long as i am on external views (eg chase, fly by views), it renders as if the CG is at the tail. When i pitch up/down, the origin seems to be the tail. I guess the external views are controlled by FG globally, is there a variable/node i can manipulate via nasal? As i was flying, i tried to change some offset positions on Sim/View node (for chase view), nothing seems to move the origin back to the ctr of the plane. and Yes, the CG of the plane is at the center as according to YASIM solver Thank you for your guidance Cheers On Monday 27,June,2011 09:29 PM, Anders Gidenstam wrote: On Sun, 26 Jun 2011, xsaint wrote: Hello All...

Much all appreciate all valuable replies and also if you could point me towards any valuable YASIM documents. Another thing to check is the alignment between the 3d model and the FDM config - make sure that your main (3d) model XML file uses the same origin as the FDM config uses. If the 3d model itself uses a different origin you will have to apply offsets in the main 3d model XML file to bring it in line with the coordinate system of the FDM config. Note that shifting the main model origin will affect the locations of views and sounds too. For JSBSim FDM configs it is possible to move the FDM visual reference point, VRP, in the FDM config to match the origin of the main 3d model XML file instead, which will not affect the other coordinate systems used in FG.

[Flightgear-devel] Clarification on YASIM input (actionpt)
Hello Folks... Was wondering if any nice souls will assist clear this doubt on mine... In YASIM, what does actionpt really refers to? Is it the point the engines pull the air through? which the point will be ahead of the engines or is it the point at back the end of the engine where the exhaust takes place? OR Do we have different application for actionpt based on the aircraft we are modeling. For example, if it is a passenger jet, the actionpt is ahead of the engines and if it is a military jet, then the actionpt is behind the nozzle?

Re: [Flightgear-devel] Clarification on YASIM input (actionpt)
Thank you Emilian and Buck Ok i tested changing the location of the point to ahead of the engine and also behind the engine, near exhaust. Irrespective of the location, looking at the results at the Yasim solver, i do not see much impact. Surprisingly i do not see any change to Drag Coef or lift ratio. The only slight change seems to occur rightfully at Tail incidence and approach elevator... Is this how it is ment to be?
