Hi!
I'm using Msc.Patran (with Marc solutor)to analyse a tape spring.
In the model, the 2 ends of the tape spring are constraint as follow:
T1 <0 0 0> R1 < , 0 0>
T2 <0 0 ,> R2 < , 0 0>.
The boundary conditions are applied on indipendent nodes of MPCs.
I must apply rotations at the same nodes...
I tried all available methods: fixed, arc length method, adaptive..
If I use the Auricchio's model for SMAs, the analysis converges. If I use 2d-orthotropic or isotropic models, the analysis doesn't converge (exit number 2004 with the message:
The determinant of the stiffness...

Hy!
I'm using Msc.Patran (Marc solver) to model a CFRP-tape spring. I use a 2D-orthotropic material to model CFRP, but this message appears in .out file:
**** note ****
can not find the following flow-data file
in job directory or in the material...
