I need to apply a sinusoidal load on a beam. I am using APDL to do it. How do I set this load at Ansys APDL ?

Hi did you found the solution

Hi

See the SFEBEAM command.

This shows some ways of doing this (there is a script there that uses an equation).

/forum/forums/topic/uniformly-varying-load-with-function/

(just change in the above link the sfbeam command to:

SFBEAM,i,2,PRES,10000*SIN((XI*3.14)/L),10000*SIN((XJ*3.14)/L) ! Apply pressure)

All the best

For linear load (selects a named selection called beam1).

CMSEL,S,beam1,ELEM

*GET,ECOUNT,ELEM,,COUNT              ! Get total number of elements

 

ELi=0

 

*DO,i,1,ECOUNT,1

ELi=ELNEXT(ELi)

*GET, EI, ELEM, ELi, NODE, 1 ! Find first node

*GET, EJ, ELEM, ELi, NODE, 2 ! Find second node

*GET, XI, NODE, EI, LOC, X, ! Find x coordinates

*GET, XJ, NODE, EJ, LOC, X, ! Find x coordinates

SFBEAM,i,2,PRES,(XI),(XJ) ! Apply pressure

*ENDDO
