[Xansys] Natural / Isoperimetric coordinates of a point in a

[fayaz.sofi]

Dear Members,

I am intending to find isoperimetric coordinates (r,s,t) and the element number that contains a point having known coordinates in active coordinate system as (X,Y,Z).

Using undocumented command below I am able to do it, however same command does not work when the active coordinate system is changed to a different one and using accordingly new coordinates (x',y',z') of the same point.

I request is there any other way in ANSYS to solve this issue other than using Jacobian Matrix and scripting by basic formulas of book.

*MOPER,Eloc(1,1),XYZ(1,1),INTP,Elem(1)
where:
*dim,XYZ,array,nPts,3
*dim,Elem,array,nPts
*dim,Eloc,array,nPts,3

Thanking you,

Sincerely,

Use *voper,,,global
To transform your local coordinated to global before using *MOPER
