![]() On the bottom edge I am applying a constant heat flux (505253 W/m2), on the same edge I am applying an emissivity of 0.47. ![]() Once you evaluate the results, the total heat value is shown in addition to min and max. Good people of ANSYS Learning Forum,nI have a 2D axisymmetric model i.e. Enter the Expression for the User Defined result as EHEAT. Create a new User Defined result and scope this face. For 3rd method, if the face is an interface between two bodies connected to each other via Share Topology, the above suggested method will not work and will yield 0, as the contribution coming from both the bodies is opposite and will cancel out. The periodic corrugated upper wall is thermally insulated and uniform heat flux is imposed on the bottom flat wall. I use the WB 19.2 and here the steady state thermal analysis. I tried to use Ansys workbench to get the thermal. 2458/5000Hello everybody,I have a problem evaluating my simulations and hope you can help me. I'm feeding the 3D model with a circuit and I found the dissipated power on the outer rings to be 18.67 W and the dissipated power on the middle ring to be 16.74 W. Solve heat simulation needs with stability and reliability using Lumerical HEAT. ![]() ANSYS FLUENT uses Equation 7.3-47 and your input of heat flux to determine the wall surface temperature adjacent to a fluid cell as (7.3-49) where, as noted above, the fluid-side heat transfer coefficient is computed based on the local flow. I'm currently using HFSS to find the dissipated power in 3 metal rings as seen in the figure below. If it is neither case 1 or 2, you can simply insert a force reaction probe and change the scope method to “Geometry” and scope those surfaces to get the heat reaction. When you define a heat flux boundary condition at a wall, you specify the heat flux at the wall surface. There is available ACT moving heat flux extension that saves time and is really useful but I could not use for shorter path like 2 mm when it moves in 5m/s so one needs to create more path or a loop structure or any sweeping properties but I do not have access any values of this extension that is the main drawback. If you have a boundary condition (temperature, convection or radiation) scoped to surfaces and you need heat flow at these surfaces, again, drag this boundary condition and drop on to the Solution to create a reaction probe which gives you total heat. If you need heat flow at the interface and you have a contact at this interface, you can simply drag this contact and drop on to the Solution to create a reaction probe which gives you the total heat. Before solve, please set “Nodal Forces” to “yes” in Analysis settings –> Output controls (needed for case 1, 3 and 4).
