bend#
- Piping.bend(nel1='', nel2='', rad='', ndiv='', estrt='', einc='', **kwargs)#
Defines a bend in a piping run.
Mechanical APDL Command: BEND
- Parameters:
- nel1
str Element numbers of the two intersecting straight pipes. Defaults to the last two straight pipe elements nearest the intersection of the last two runs.
- nel2
str Element numbers of the two intersecting straight pipes. Defaults to the last two straight pipe elements nearest the intersection of the last two runs.
- rad
str Bend radius. If LR, use long radius standard (1.5 x nominal diameter) (default). If SR, use short radius standard (1.0 x nominal diameter).
- ndiv
str Number of divisions (elements) along bend (defaults to 2). A node is generated at the end of each division.
- estrt
str Number to be assigned to first element of bend (defaults to MAXEL + 1).
- einc
str Element number increment (defaults to 1).
- nel1
Notes
Defines a bend of curved (elbow) pipe elements (PIPE18) in place of the intersection of two previously defined straight pipe elements (RUN). Two new nodes are generated at the ends of the bend (at the tangency points). A node is also generated at the center of curvature point. The two straight pipes are automatically “shortened” to meet the ends of the bend. The bend specifications and loadings are taken from the corresponding two straight pipes. The flexibility factors are calculated from the internal pressure and EX (evaluated at TAVE) based on the current PPRES and PTEMP command specifications when the element is generated.
