Problem in meshing a plate (thermal problem)

  1. Jan 18, 2012 #1
    Hello, I’m trying to solve the following problem: a composite plate with circular steel in the lower left corner. The upper and lower surfaces are insulated, on the right the temperature is constant, and on the left exits natural convection. The analysis is steady-state.
    I’m using a quadrangular element. The problem occurs when I mesh the plate and the circle, as is visible in the following image; the nodes of the circle aren’t the same as the plate, around the surface of the circle, so when I solve the problem the temperature of the circle doesn’t change.

    The image is in the attachment.

    I wonder if anyone knows how I can mesh the problem on obtain good results.
