Capacity Matrix - transient heat

    Initial Nodal Temperatures

    Please Help,

    I am learning how to do 2-D time-dependent linear heat conduction for Finite Elements, and am progressing but have a question with nodal heat values.

    I am using the explicit Euler Forward Difference algorithm and as such need to set initial nodal temperatures in the solution vector. Can the initial nodal temperatures be set to 1? I have some boundaries in the model (convection edge, and specific temperatures at a couple of nodes), should these values come into play for the initial nodal temperatures?

    Thank you for any help.
