hello
well, that's exactly it
thanks!!
i will have to be a little bit more clever in the design of the loops to
create the geometry in this case
it would be much easier if i wecould tell
Line (10x) = Rotate [ .... {Duplicata { Line {100};}]
enforcing the value 10x instead of letting Gmsh use newl
Hi Jean-Pierre,
it was possible before, but it created far more problems and had many side
effects...
a way of retrieving the number of the two ends of a line would be useful too
http://www.geuz.org/gmsh/doc/texinfo/gmsh.html#Transformations
Boundary { transform-list }
(Not a transformation per-se.) Returns the boundary of the elementary
entities in transform-list.
with
transform-list:
Point | Line | Surface | Volume { expression-list }; ... |
Duplicata { Point | Line | Surface | Volume { expression-list }; ... } |
transform

Subject: Re: [Gmsh] gmsh fails to create points inside a loop
Though I havent had time to review your code explicitly, I know one
possible stumble...
Gmsh can not create two points at the exact same point in space(in
addition to not having the same identifier). This is a likely mistake
when using loops, and I find myself running into that problem
frequently.
Hope that helps,
Eric

hello
i have the following loop to create an axis symetric struture
For i In {0:num:pas}
.........................
Point(10000*i
+100538)={-5800*Cos(a*i)-(0*Sin(a*i)),-5800*Sin(a*i)+(0*Cos(a*i)),6060,e};
Point(10000*i
+100701)={-4435*Cos(a*i)-(30*Sin(a*i)),-4435*Sin(a*i)+(30*Cos(a*i)),8766,e};
Point(10000*i
+100702)={-4435*Cos(a*i)-(-30*Sin(a*i)),-4435*Sin(a*i)+(-30*Cos(a*i)),8766,e
};
..........................
EndFor
for i =0 all 3 points are created
for the next st ps the point Point(10000*i+100701) is not created
and this happens at a few other places within the loop which contains
about 150 point to be repeated 16 times
the point can however be created outside of the loop with the same
parameter
any idea of what's happening
i wnat to create a structure similar to this one which was created with
gmsh, many thanks!!

but much more complicated and largelly parametric
