Hello, I have a doubt about the output of the solution. I can't understand why the momentum diagram comes out like this, in steps (like a bar graph).
I don't know if I moved some setting or I'm doing something wrong but before it came out without discontinuity.
Could you help me figure out what to do?
I attach a photo.

You need to use the quadratic version of beam188 like in the test below:

/prep7

et,1,188,,,2               ! Default beam188 only has one Mz, same at both ends

mp,ex,1,3e7

mp,nuxy,1,0.3

sectype,1,beam,rect

secdata,1,1

 

n,1

n,11,20

fill

 

e,1,2

*repeat,10,1,1

d,1,all

f,11,fy,100

 

fini

 

/solu

solve

fini

 

/post1

set,last

etab,mzi,smisc,3

etab,mzj,smisc,16

plls,mzi,mzj
