Reference vector
Hi! I have implemented typ 16 property for a fabric material and now creating a material card from tensile test results. I am a bit confused of the ref vector in the property card. I understand, if Vx =1 the direction of fiber is aligned with global X-axis, but how will it assign the x-axis of fiber to global axis?
What happens with the other cases, if
vx=0 ; vy=1; vz=0
vx=1; vy=1;vz=0
I have performed the tens. test by having a fabric(warp, weft fibers separated 90deg) whose warp and weft are parallel and perpendicular respectively to the loading direction.
Any answers regarding this are highly appreciable. Thanks in advance

Attached are the images, where axis 1 & 2 define the fiber direction 1 & 2 respectively and L is the loading direction. So I would assume these values
case1: vx=1; vy=0; vz=0 ( or should it be vx=0; vy=1;vz=0)
phii = 0; alphai =90
case2: vx=1; vy=1; vz=0 with phii=0
or is it something different?
I am sorry if I am totally wrong, because I am a bit confused even though reading the manual.

Altair EmployeeHi Ushay,
As you told for reference vector if we assign Vx=1 and Vy=Vz=0, the direction of fiber is aligned with global X-axis.
If Vx=Vy=1 and Vz=0 is provided it will take the resultant vector.
It's always recommended to create a local skew and assign the same for different orientation.
Got it George!
Thank you very much
Currently I am running with Vx=1; vy=0; vz=0.
If the fiber axis are not loaded parallel to one of the fibers then local skew would help me, but i'm a bit curious with other conditions as
vx=0 ; vy=1; vz=0
vx=1; vy=1;vz=0
