    Finite difference method - GETVRM and UEXTERNALDB

    Dear all, I need to implement the general heat equation (which is a differential equation) through a numerical method - finite difference method. To do that, I have to access the temperature of the adjacent elements. Anyone know how to do that? I have tried to use the utility routine GETVRM...

    Heat generation with user-subroutine UMATHT

    Dear all, Does anyone know how to incorporate heat generation in the user subroutine UMATHT? I cannot use HETVAL since I want to redefine thermal material behavior and this required the use of UMATHT. The Abaqus documentation states that UMATHT can be used to apply internal heat generation, but...

    Implementation of resin kinetic model using HETVAL and USDFLD in Abaqus

    Dear all, I need help to implement a resin kinetic model based on an equation of Arrhenius type to simulate the curing process, using Abaqus. The corresponding analytical model quantifies the dependency of the rate of the degree of cure dα/dt with the temperature T and the degree of cure α, as...
