    Differences of solution dependent variables in different abaqus subroutines

    Hi, Abaqus has state variables in subroutines (UMAT, UINTER,UEL,etc.). My question is what is the difference the state variables between different subroutines. Consider the case where UMAT and UINTER are both applied in a model. 10 state variables are defined in UMAT and another 5 state...

    Why the strain varies with mesh size?

    Hi, I have calculated a case that the material bears surface traction. When I did the mesh sensitivity, the output max log strain increased from 0.133 to 0.741 with the element size decreasing from 0.5 to 0.03? I can't understand this result. Can you help explain the theory inside this...

    How to define initial stress in 3 dimensional model with a cylindrical coordinate

    Hi, I am modelling a cell contraction on a layer of substrate. The cell model is axisymmetric (but I didn't model it with axisymmetric modelling space) and I want to apply a initial stress (in predefined field) to simulate the cell contraction force towards the cylindrical centre. So how...
