Two boundary conditions on one surface

Hello everybody,
I am trying to simulate a high heat flux part of a reactor, and at some surfaces i have two different surface heat loads (W/m2) which i have to consider. I cannot just add the values in those areas since they are profiles(x,y,z coordinates and heat value). Does anybody know if this is possible? I am trying to create the named selections for those boundaries while meshing, and since they overlap at the surfaces with both heat-loads, i can't even export from Meshing. Summing up, i would like to apply two surface heatloads on a single surface Any help is kindly appreciated! Thanks |

You can import the heat loads as profile data into Pre. Then you have an expression referencing your profile data.
Write another time-dependend expression like "If(t <= 1 [min], profiledata1, profiledata2)" referencing those profile-data-expressions. You could use step-function as well. Then apply your time-dependend expression to the BC. |
