VUSDFLD VGETVRM

[V_S_B]

how to use VGETVRM to get temperature , strain and strain rate valuues?

 

[FEA way]

The interface of VGETVRM utility routine is:

call vgetvrm( 'VAR', rData, jData, cData, jStatus )

Data is provided to this routine via output variable key VAR. Available output variable keys that can be useful for you include:
LE - logarithmic strain components
PE - plastic strain components
TEMP - temperature

Unfortunately strain rate (ER) is not available in VGETVRM.

An example of the use of this routine for logarithmic strain components is:

call vgetvrm( 'LE', rData, jData, cData, jStatus )

@FEA way
Thank you for your reply.
Is there any method to get strain rate ER.

 

[FEA way]

I'm afraid that the only way to bypass this limitation is to use Abaqus/Standard and USDFLD instead of VUSDFLD. That's because GETVRM utility routine used in conjunction with USDFLD doesn't have such limitation regarding available output variables.

Can someone please explain what is wrong with this code.
I need to add two new parameters if my current strain is greater than the critical strain (whose value depends on peeq temperature and strain rate)
