Thanks Bill, that was really helpful.
Actually I've another question about the smoothed-polygon mapping. I usually
create them with a routine similar to the following one:
***********************************
smoothedPolygon
vertices
5
0. -0.025
1.0 -0.025
1.0 0.025
0. 0.025
0. -0.025
n-dist
fixed normal distance
-1.0
lines
250,150
boundary conditions
-1, -1, 1, 0
n-stretch
2. 10. 0.00001
exit
***********************************
and I think that the leading edge should be in the origin. Is that so, or the
smooth function makes the mapping a bit "longer" and it is somehow shifted?
I do appreciate your help,
Alessandro

Hi Alessandro,
When you restart from a showfile the properties of the moving bodies
are also
read from the showfile, including the constraint. Unfortunately there
is currently
no easy way to change these values. I will add an option to allow
changes.
In the mean time, as a work around you could try one of these options:
Option 1. (not sure if this really woks or not)
1(a) restart with motion OFF and save the solution at t=0 in
a new show file.
1(b) restart with motion ON using the show file from step
1(a).
Option 2. Edit the file cg/common/moving/src/RigidBodyMotion.C and
change the "get" function and turn off the constraint after it is
read in
from the show file: (around line 1680)
subDir.get(temp,"positionConstraint");
positionConstraint=(PositionConstraintEnum)temp;
positionConstraint=positionHasNoConstraint; // **** add me ***
I hope that helps,
Bill.

Hi all,
I run a simulation in which i had only 1 degree of freedom, and now I
want to begin a new simulation starting from the final conditions of
the first one, but with 3 degree of freedom.
If I use the option "initial condition - read from a show file" does
overture set the same degree of freedom of the old simulation (e.g.,
position is constrained to a line) or this is a user choice?
Thanks!
Alessandro
