Hey there,
I do a transient structural mechanics in ANSYS Workbench and want to export the results of a defined path for each time step. Can anyone help me with this command?
Thank you so much

Hi Oliver,

Here is an example that allows you to export the temperature along a path at all the different sets:

"
set,first

node2=node(0,0,0) !Take the nodes loc to create the path
node1=node(1000,1000,1000)

PATH,TPATH,2,30,51 ! DEFINE PATH WITH NAME = "TPATH"
PPATH,1,node1
PPATH,2,node2

PDEF,temper,temp,,AVG !Interpolate the temperature
PAGET,temper1,TABLE

*GET,nline,PARM,temper1,DIM,1 !retrieve the number of values of the paget table
*GET,nsets,ACTIVE,0,SET,NSET

*DIM,PATHtemp,array,nline,nsets+1

*do,i,1,nline !copy paste the values we need

PATHtemp(i,1)=temper1(i,4)

*enddo

*do,i,1,nsets ! do it for every time

PDEF,CLEAR
PDEF,temper,temp,,AVG
PAGET,temper1,TABLE

*do,j,1,nline
PATHtemp(j,i+1)=temper1(j,5)
*enddo

set,next

*enddo

*MWRITE,PATHtemp(1,1),RESULTS_Pathtemp,txt,,JIK,,, 1 !write it on a file
(98(F15.10))

"


You can simply change the temperature to the field variable you need using the APDL guide.



Have fun

Thats my APDL-Command, but it not really worked, does anyone find what's wrong? I put the command in the solution process in workbench. And where can I find the .txt file to be output?



/POST1
node2=node(100,0,0)
node1=node(100,50,0)
PATH,TPATH,2,30,100
PPATH,1,node1
PPATH,2,node2

PDEF,PfadSigX,S,X,AVG
PAGET,PathData,TABLE
*GET,nline,PARM,PathData,DIM,1 !retrieve the number of values of the paget table
*GET,nsets,ACTIVE,0,SET,NSET
*DIM,PATHSig,array,nline,nsets+1

*do,i,1,nline
PATHsig(i,1)=PathData(i,4)
*enddo
*do,i,1,nsets ! do it for every time
PDEF,CLEAR
PDEF,PfadSigX,S,X,AVG
PAGET,PathData,TABLE
*do,j,1,nline
PATHsig(j,i+1)=temper1(j,5)
*enddo
set,next
*enddo
*MWRITE,PATHsig(1,1),RESULTS_PathSig,txt,,JIK,,, 1 !write it on a file
(98(F15.10))
