Stable time increment control ERROR 1

[jorge0894]

Hi everyone,
I'm working on compression test simulations with a material model defined by a VUMAT. However, my simulations are not running since the following error appears:

***ERROR: There is no element available in the model to control the stable
time increment for Step 1. Please add a deformable element to
control the stable time increment. Alternatively, you can use DIRECT
TIME INCREMENTATION to perform the analysis at a user specified time
increment.
I don't know why this is happenning, if anyone could know why, I would appreciate the help. And if you need to know some more info about the simulations just tell me,
Thank you in advance,
Jorge R.

It seems that your VUMAT code is incorrect - Abaqus needs deformable material properties to calculate stable time increment for the analysis.
