Hello everyone,

I am looking for a way to get a mass distribution of my complete ACP model along an axis. Is there any way to get this somehow easily in ACP or Mechanical?

My second thought would be to do scripting in APDL or PyMAPDL by selecting elements by ranges in a z-direction, get mass, divide by the range length to get the specific mass. Then continue to next range until covering all the model.

Is there a way to export this to a table in Workbench?

 

Any thoughts or suggestions are welcome.

 

Best wishes

You can try with below APDL script

/prep7
ESEL,S,ENAME,,Solsh190 
*get,emin,element,,num,min
*GET,noelems,ELEM,0,count,
!e=emin
e=76271
*DIM,data,ARRAY,noelems,4
mass=0
*do,i,1,1,1
    *GET,volu1,ELEM,e,VOLU, 
    *GET,sec1,ELEM,e,ATTR,SECN
    *GET,thickness,SHEL,sec1,PROP,TTHK,
    *GET,nooflayer,SHEL,sec1,PROP,NLAY,
    thick=0
    emass=0
    *do,j,1,nooflayer,1
        *GET,lay%j%,SHEL,sec1,LAYD,j,THIC
        *GET,laymat%j%,SHEL,sec1,LAYD,j,MAT,
        *GET,density%j%,DENS,laymat%j%,TEMP, ,
        emass=emass+volu1*density%j%*(lay%j%/thickness)
    *enddo
    data(i,1)=e
    data(i,2)=thickness
    data(i,3)=volu1
    data(i,4)=emass
    e=elnext(e)
    !*GET,e,ELEM,e,NXTH,
    mass=mass+emass
*enddo
my_mass=mass
allsel,all
/post1

It is a sample script that calculates the mass. You can modify it as per your needs.
