Need help with sim-file

[pontius]

Moin,

Im trying to adjust the simfile for a new ship.
I was looking into it, changing speed, power and RPM without problems.
But now the problems:
When giving the correct "displacement", the ship is sinking like a stone and i have to put in "0".
When giving the corrct "draught", the ship flips over and is sinking too, so i also have to put in "0".
Do I have to convert measures or something like this?
Also i get no clue about "mass", "gc_height" and "fr_ratio". :hmm:

Einlightenment would be appreciated :yep:

Thanks in advance,
pontius

mass The object's mass [Tons]. If 0, then the object's surfaced displacement is taken.
gc_height Gravity center height from the object's bottom [m]. If 0, then the half of geometric bounding box is taken.
fr_ratio Gravity center horizontal position [>0]. 1=FRONT, 0.5=MIDDLE, 0=REAR.
displacement The object's displacement [Tons]. If 0 then the object's mass is taken.
draught The object's draught [m]. If 0, then it is taken from the object's global position.

The best advice is as BB said is to look in a similar sized existing ship sim file and copy the parameters to give you a good start, then you can finbe tune from there, remember though that real life values not always provide the desired results in the game.

Thank you very very much ref!! :up:
Now my tweaking gonna be much more controlled :)

For stock SH3 she moves quite ok now, but in GWX she is dancing , and sometimes to heavy .lol But now it can go further.:rock:

Thanks,

Try increasing a bit the mass and lowering the gc_height, just try with small changes at a time, it's a tedious work, but the only way to do a good work.
