I made the above changes & all is well for 1 single-block data file.
When I try to plot a multi-block file (3 blocks, created by appending
each block's worth of grid & dependent variables to the previous one,
beginning w/ the DIMENSION statement), I get errors & only the 1st block
gets plotted. The connection between blocks looks like:
3.001464422823146E+01 -2.066312618121650E-02 0.000000000000000E+00

with the end of the (U,V,W) data of block 1 preceding the DATASET
statement for block 2 & so forth for N blocks. I get the following when
I try to plot this file:
[EMAIL PROTECTED], test, 7:25:52am] 397 % mayavi -d TadMBDbg.VTK

The 1st try above, I had duplicated everything including the DATASET
statement for each block. The 2nd try, I deleted the last 2 DATASET
statements w/ vi & tried again. Each time, I got a plot of the 1st block
OK, but nothing else. The 'configure data' button listed 3 blocks worth
of dependent variables, & had the 1st checked/active for all 3 blocks,
but it only plotted the 1st block.
More pilot error, I'm sure :-). Clues ? TIA ....
