Hi all friends:
I am modelling a round bar under axial compression, and want to impose pressure to the body through out the lateral surface, and I want the magnitude of the pressure varies along the axial direction of the bar, I cannot find any suitable way to give this load in the list of load module, can anyone help me how I can implement this pressure ? need to edit subroutine to the input file?
Thanks very much!
Sincerely yours,
Mengli
Hi,
I think the simplest way to define a variation in load magnitude along one direction is to use an analytical field. Just define your analytical field with a function of the longitudinal direction, and within the load module you can select your field, as opposed to the load magnitude being constant. That being said, for more complex load distributions, I guess you will have to use a user subroutine.
Hi There, It would be good to learn what analysis system are you using? Regards, I.H.

Hi,
if you would prefer ANSYS, you can use APDL for that job. In case of MARC and ABAQUS you should use a subroutine. And for the case of NASTRAN I would prefer a PATRAN script.

Sorry all of you, my mistake, I am using ABAQUS with post buckling analysis, thanks very much!
