FEM modelling of oblique bend (MSC Marc mentat)

FEM modelling of oblique bend (MSC Marc mentat)

FEM modelling of oblique bend (MSC Marc mentat)

I am modeling oblique bending of a rectangular beam. Bending during creep. No fatal errors, but 13 errors appear
when compiling.

13 exit message:
Data errors have been detected during data input. Refer to
output for location of error. Likely causes are misspelled
keywords, mistyped lines or invalid input options.

With what may be this is due?

RE: FEM modelling of oblique bend (MSC Marc mentat)

Seems like error in model definition. If you didn’t change any keywords manually then something is wrong in the analysis settings.

However, it’s difficult to distinguish the boundary conditions in the picture. Could you attach more images showing the beam from both sides ? Also it would be better to fill the entire picture with the beam and describe boundary conditions in the post.

RE: FEM modelling of oblique bend (MSC Marc mentat)

1. at the end of the beam - torec- displacement z=0,rotation x=0;
2. on the other side of the beam - x=0 - displacement x=0;
3. fixed lines - f - all boundary conditions are 0;
4. bending moment - press - moment x =-16000;

materials creep: user sub. crplaw;
analysis options - large strain;
rbe2- dof - 1,3,5,6 (tick)


rectangular beam under pure bending was considered before.
There were no errors in the account.

RE: FEM modelling of oblique bend (MSC Marc mentat)

Have you tried running this analysis without creep subroutine ? Are there any differences in settings of these two analyses (pure and oblique bending) apart from boundary conditions ?
