[CIG-SHORT] Initial stress cell_data_fields settings and interpolation

[Chunyu Liu (cliu5)]

Hi all,

Is there any way I can get initial stress data( not that resulting stress)  in .VTK file?
I do not find any settings for the initial stress in “ cell_info_fields” and “cell-data_fields”.

For example:
cell_data_fields =[ stress, “stress_initial”]


Q2: Interpolation problem

1.   I use linear interpolation.
2.   several initial stress lines. For example:

// Columns are
 25 // (1) x coordinates(m)
 26 // (2) y coordinates(m)
 27 // (3) z coordinates(m)
 28 // (4) stress-xx (Pa)
 29 // (5) stress-yy (Pa)
 30 // (6) stress-zz (Pa)
 31 // (7) stress-xy (Pa)
 32 // (8) stress-yz (Pa)
 33 // (9) stress-xz (Pa)

3. the result looks like this. It has some pattern.  I want to get rid of this pattern.
