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...
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...
Many thanks. I solved my problem saving the variables into field() and statev() inside the USDFLD subroutine.
Now, I have other question: Is it possible to use the HETVAL subroutine in a explicit analysis? I test the subroutine in a standard/implicit analysis and works fine, but now I need to...
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...
