mapping of stress
 

hey there,

I have a problem with my ansys.

I want to map some values (yield stress) on a geometry. I´m a beginner and now i dont know where my mistakes are.

i have a csv-file with my informations. ´
for example yieldstress.csv :

x;y;z;yieldstress
1;3;3;800
2;2;7;700
3;3;2;850
4;23;8;800

now i tried to get coordiantes of the nodes and put them into an array (new geometry)

*get,mpmax,mat,0,num,max !number of nodes

*dim,nadata,array,mpmax,4 !Def. of Array ndata
*vget,nadata(1,1),node,0,loc,x ! x coordinates
*vget,nadata(1,2),node,0,loc,y !y coordinates
*vget,nadata(1,3),node,0,loc,z ! z coordinates
*vget,nadata(1,4),node,0,stress !yield stress


then i tried to put my new infromations of flgr.csv into a array


*dim,flgr,array,9000,4 !Def. of Array flgr
*vread,flgr(1,0)=1,yieldstress,csv,0,1,9000 ! x coordinates
*vread,flgr(1,1)=1,yieldstress,csv,0,2,9000 ! y coordinates
*vread,flgr(1,2)=1,yieldstress,csv,0,3,9000 !! zcoordinates
*vread,flgr(1,3)=1,yieldstress,csv,0,4,9000 !new yield stress

than i tried to interpolate the yield stress on the new mesh

*moper,nadata(1,4),map,flgr,3 !mapping of the yield stress



it doesnt work. i know there are some mistakes but i dont know where.

sorry for my bad english :)

maybe better
 

so maybe i found some mistakes. I think i have to put the infromation about the coordiantes and the yield stress in two different arrays

"*MOPER,ResVal(1,1),ResXYZ(1,1),MAP,InVal(1,1),InXY Z(1,1),kDim
kDim = 2, 2d (shell) 3, 3d (solid)
ANSYS 5.7 has a MAP option which will:
Given: A set of points InXYZ(nPt,3) and a value(s) InVal(nPt,nVal) at each point
A second Set of points ResXYZ(nOut,3), contained within the geometry of the first set of points.
Determine the value(s) ResVal(nOut,nVal) at each point in the second set."

so i have now:


!new mesh:

*get,mpmax,mat,0,num,max !number of nodes *dim,nadata,array,mpmax,3 !Def. ofArray ndata

*vget,nadata(1,1),node,0,loc,x
*vget,nadata(1,2),node,0,loc,y
*vget,nadata(1,3),node,0,loc,z

*dim,Yielstr,array,mpmax,1
*vget,yieldstr(1,1),node,0,stress


!old Data (9000 Points)

*dim,flgr,array,9000,3

*vread,flgr(1,0)=1,yieldstress,csv,0,1,9000
*vread,flgr(1,1)=1,yieldstress,csv,0,2,9000
*vread,flgr(1,2)=1,yieldstress,csv,0,3,9000


*dim,Yielstr,array,mpmax,1

*vread,yielstr(1,1)=1,yieldstress,csv,0,4,9000


!mapping:

*moper,yielstr(1,1),nadata(1,1),map,yieldstr(1,1), flgr(1,1),3

maybe its better but it doesnt work :(
