Hi,
I am trying to use the ABAQUS/standard solver to simulate the single crystal deformation behaviour with DAMASK framework. The materials is BCC ferrite with hooke elasticity and phenopowerlaw plasticity. The model is a 2D cube with a mesh element type CPE8. Boundary condition: left U1 constrained,, bottom U2 constrained, and top with minus V2.
The job ran without errors, but there are many 'position not found when parsing line' warning in the .dat file and 'THE SYSTEM MATRIX HAS xxx NEGATIVE EIGENVALUES. ' in the .msg files. What is the question?
I am new to DAMASK and have insufficient experience. Any suggestion would be greatly appreciated.
Attached are the INP, MSG, DAT and STA files.
Thanks.
