- valueThe value to be set in IC
C++ Type:double
Unit:(no unit assumed)
Controllable:No
Description:The value to be set in IC
- variableThe variable this initial condition is supposed to provide values for.
C++ Type:VariableName
Unit:(no unit assumed)
Controllable:No
Description:The variable this initial condition is supposed to provide values for.
FVConstantIC
Sets a constant field value.
Sets a constant initial condition described by parameter "value". It can be restricted to particular blocks using the "block" parameter.
Example input syntax
In this example, a blockwise constant initial condition is set for variable u. Block 1 and 2 are set differently by two FVConstantIC objects.
[FVICs]
[ic_u_1]

variable = u
value = 6.25
block = '1'
[]
[ic_u_2]
type = FVConstantIC
variable = u
value = 9.99
block = '2'
[]
