    Error with abaqus subroutine

    Only limited unit number (from 1 to 100) can be used. most are reserved. Try something larger than 100.

    Phase Transformation+HETVAL+USDFLD

    USE state variable, SDVn, n=1,2,3

    how can i obtain the stiffness matrix

    You can request in the input.

    Usermat

    Go with 1 element test first. Check: 1) stress update in umat;2) Jacobian Contact abaqusDr@gmail.com with input, umat and reference papers for umat if you do need help

    excessive distortion when the model has't deformed at all!

    Two solutions: 1) add stabilizie to *step 2) add contact controls,stabilize

    Running multiple subroutines for analysis

    Put all subroutines in the same file

    How can I apply a known residual stress field to a model?

    Since you have only discrete mises stresses, it is hard. If you can somehow get the stress components, then using *initial conditions,type=stress.

    Stress Softening in UMAT

    That means your UMAT is not properly writen. Strain softening is not the direct cause. Check your jacobian.

    Excessive deformation in flow forming process

    100Sec is too large to use xpl. Try std, contact pair, surface to surface, finite slide contact.

    how to calcualte total reaction force in a plane in ABAQUS

    Viewer can do that.

    Very large deformation - Poor Mesh Ratio - Remeshing Script

    I did this before. Use python to extract the exterior boundary of the deformed specimens and call cae mesh modulus after in the same python. Then you can play with the newly generated mesh with whatever you want. Contact abaqusdr@gmail.com if you want further help.
