    Stress values different for VUMAT and Abaqus built-in material

    Hi! I'm running simulations of composite laminates under impact loading. An example of VUMAT is uniFiber.f. https://cnzhx.net/fe/2015/05/09/an-example-of-vumat-using-hashin-criteria-for-composites/ At the first step, I only conduct linear elastic analysis without any damage. The element used is...

    MPC constraints

    When I used *MPC with more than 15 nodes in the data line, the number of characters in one line will exceed 256. The node set I considered is from instances so that Abaqus will automatically add a prefix of 'Assembly_'. I tried fewer nodes one line. But it seems Abaqus will ignore the...

    Dynamic analysis with linear and quadratic element

    Hi, I am simulating a bar (Abaqus implicit dynamic) which is loaded at the right end while fixed at the left end. The displacement imposed at the right end is a cosine function, which lasts for one period. The results were different when I used linear and quadratic elements. What may be the...

    Transient heat transfer

    Hello, I am running a transient heat transfer simulation with a quadratic element (DC2D8). The temperature of the left edge is fixed at 0 while the right edge increases gradually to 45. But I found the temperature of the left half is lower than 0. Is this reasonable?
