Hi everyone,
I am trying to solve a problema of heat transfer in which
there is an inner heat generation (Q). I know that Abaqus has a subroutine
called HETVAL in which this procedure is very easy to implement, but for other
porpuses later on I need to do using a UEL subroutine.
I have the equations for the RHS and AMATRX of the UEL, and
it works perfectly well if Q= constant value. But in my case, Q depends of the
variable of the problem (temperatura) that in the UEL subroutine are in the
vector called U. In this point is when I don’t know how to go on, as the
dimensions of the matrix don’t match well.
Hope someone can help me with this. Thank you very much in
advance.
P.S: look the file attached with some notes about the
problem I am trying to solve in case it helps to understand it better.
