Hi everyone, I am working on a system and trying to relax canted angle calculations (starting from 25 degrees and then relaxing the angle)using the following nocoinp file
atom-type 1,l_relax=F
alpha = 0.0000000000,b_cons_x = 0.0000000000
beta = 25.0000000dg,b_cons_y = 0.0000000000

atom-type 2,l_relax=F
alpha = 0.0000000000,b_cons_x = 0.0000000000
beta = -25.0000000dg,b_cons_y = 0.0000000000

atom-type 3,l_relax=F
alpha = 0.0000000000,b_cons_x = 0.0000000000
beta = 25.0000000dg,b_cons_y = 0.0000000000

atom-type 4,l_relax=F
alpha = 0.0000000000,b_cons_x = 0.0000000000
beta = -25.0000000dg,b_cons_y = 0.0000000000

atom-type 5,l_relax=F
alpha = 0.0000000000,b_cons_x = 0.0000000000
beta = 25.0000000dg,b_cons_y = 0.0000000000

atom-type 6,l_relax=F
alpha = 0.0000000000,b_cons_x = 0.0000000000
beta = -25.0000000dg,b_cons_y = 0.0000000000

--- logical parameters --
l_ss=F,l_mperp=T,l_constr=F
mix_b= 0.500

however, i am facing this error

"rot_den_mat: rotation of mag. failed"

Is any one have an idea how can i resolve this issue?

PS. i am using OLd v26 version

I think meanwhile this routine was made more stable to avoid that error.
I attach the new subroutine that you can exchange for the old one.
(I had to add .txt to the filename to allow uploading)
