With the fixed temperature value boundary condition, a prescribed constant or variable temperature value can be applied to the assigned entities (faces or volumes). This is useful to model constant temperature heat sources or sinks, or to apply a known spatial distribution of the temperature field.
The parameters of the boundary condition are:
Application Hints
The following analysis types support the usage of this boundary condition:
Being a fixed temperature is not the same as being a constant temperature. With this boundary condition, the fixed temperature can vary with respect to the position in space, or with respect to time for transient simulations.
Variable temperature values can be specified with the use of the formula or table inputs. The allowed functions are:
Maximum Number of Table Parameters
Due to numerical difficulties, the underlying structural solver (Code_Aster) only supports table function definitions of one or two variables. If you need to define a function of the three spatial coordinates (X, Y, Z), or even combine it with time, you must create an analytical formula for it.
