Sam and Andy,


Thanks for your advices.
I found the order of applying filters is very important.
Here is a good step:
> 1. Extract Fluid block(s)
> 2. Cell Data to Point Data at Original Multiblock
> 3. Resample Data Sets of Original Multiblock at Fluid Block(s)

Most cases are OK with above step, but some cases including
non-contiguous interface failed on resampling step
(mismatching about Tuple Length).
