Active DOF
Active DOF
(OP)
Could anyone be so kind to give a newbie, me, a short or detailed explaination of Active DOF? what is it? And how to use?
My problem: when I am using ANSYS to solve my problem, in the SOLU procedure, there is a warning said :
[color green]There are no active degrees of freedom.[/color]
[color green]SPARSE MATRIX DIRECT SOLVER.[/color]
[color green] Number of equations = 0, Maximum wavefront = 0[/color]
[b]Thanks a lot![/b]

If yes, then has everything been completely restrained?
Have you had any training ???
RE: Active DOF
You are right, I deleted the calculating displacement transformation part in the program, there are 2 fixed nodes, but the others should have transformations on them.
I want to simplify the programm to the possiblly least.
@johnhors
I always have the right mesh, I just do some changes in the /SOLU part.
You are right, as I said I am a newbi;I got almost no training. and I learn ANSYS, eg. APDL, by digging out whenever necessary. I even not familiar with the use of GUI, and I can model only by writing simple input files.
I am in dangerous situation now.
Anyway, thank you both so much! :)
