*NODE PRINT v6.4 and 6.2

[smg2]

I am hitting a wall to figure out this problem, and would appreciate any help from anybody. I am using a fluid element:
*NODE,NSET=NGAS
3000,0.0,-0.0025,0.0
.
.
.

*FLUID PROPERTY,REF NODE=NGAS,ELSET=GAS,TYPE=HYDRAULIC

Then I want to output the volume and pressure of this gas:
*NODE PRINT,FREQUENCY=1,NSET=NGAS
CVOL,PCAV

I can do this fine in v6.2. But I am now running the same code with v6.4 and this is what I get:
THE FOLLOWING TABLE IS PRINTED FOR NODES BELONGING TO NODE SET NGAS

NODE FOOT- CVOL PCAV
NOTE

ALL VALUES IN THIS TABLE ARE ZERO

As far as I have gathered from the documentation, no changes have been made to the commands related *FLUID. Further the history output in ABAQUS viewer works fine, giving finite values of the two variables. Could anyone please help me? unfortunately I am using an academic license and hence cannot direct my enquiries to HKS. Thanks a lot!

smg2,

On the ABAQUS website, there is a known bug listed on the status reports as error number V64_1808, which describes your problem pretty much to the letter. (A copy of the report message is shown below)

============================================

The output variables hydrostatic fluid gauge pressure
(PCAV) and hydrostatic fluid cavity volume
(CVOL) are incorrectly reported by
ABAQUS/Standard as zero in the data (.dat)
file. The correct, non-zero values appear in
the results database (.odb) and can be probed
or visualized.


IDENTIFIERS: FLUID_PROPERTY,NODE_PRINT output


This has been corrected in 6.4-3

=========================================================

As it says, its been corrected in V6.4-3. You should have access to this maintenance release as part of the academic license. Hope this helps.

Thanks!!

Unfortunately, I am running v6-4-1, not 6.4-3, so I have had to change my script file to read from the odb file instead, which turns out to be neater (and the code is much simpler) than what I have been doing all this while with the .dat file.
