FLUID CAVITY HELP in ABAQUS

FLUID CAVITY HELP in ABAQUS

FLUID CAVITY HELP in ABAQUS

(OP)
I am modelling an inflated sphere. The sphere is composed off two circular planar membranes joined together at the boundries.
I have modelled the inside of the sphere as a fluid cavity and will inflate it to its threshold limit.

I have achieved this by using the fluid cavity and fluid inflator method but for some reason when I run my input file I receive the following message:

***ERROR: THE FLUID INFLATOR ACTIVATION HAS BEEN SPECIFIED ON THE FLUID
INFLATOR ASSEMBLY_CAVITYINFLATION. THIS FLUID INFLATOR HAS NOT BEEN
DEFINED IN THE MODEL. IF A PART INSTANCE IS USED IN THE CURRENT
MODEL, PLEASE CHECK THE NAME OF PART INSTANCE FOR THE FLUID
INFLATOR. IF YOU USE THE KEYWORD FLUID INFLATOR INTERACTION WITH
PART INSTANCE, PLEASE USE THE KEYWORD FLUID INFLATOR ACTIVATION
INSTEAD.


I am not quite sure how I can overcome this as I have defined my fluid cavity in the *instance section of the code and I am defining the fluid inflator activation in the *step section of the code.

Any help or advice would be much appreciated, thanks for looking :)

RE: FLUID CAVITY HELP in ABAQUS

Hi,

I have managed to work out this error, in the new versions of abaqus you need to supply the part name before the area defined
e.g.
*FLUID INFLATOR ACTIVATION
Cavity
(this does not work). However, if your part is called 'Complete' THEN
*FLUID INFLATOR ACTIVATION
Complete.Cavity
(this works fine)

Hope this helps anyone who had a similar problem to me :)
