Advanced BC
Advanced Boundary Conditions
Advanced Boundary Conditions are used for modeling physics where User can apply a selected solution variable on the model. Advanced BCs provides more control if a particular variable needs to be provided on a set of nodes / elements.
- Nodal Boundary Condition
- Element Boundary Condition
- Surface Integrated Boundary Condition
Nodal Boundary Condition
Nodal boundary condition specifies a solution variable on a set of nodes. User can select a face or a set of nodes to apply this boundary condition. The solution variables supported are X velocity, Y velocity, Z velocity, Pressure, Temperature, and Eddy viscosity,Mesh X Displacement, Mesh Y Displacement and Mesh Z Displacement.
Four different types are supported namely Zero, Constant, Piecewise Linear, Cubic spline and Nodal Values. Type of Zero is selected if the solution variable must be set to zero. Constant type can be used to provide a constant value. Piecewise Linear type can be used to provide a varying solution variable as a function of another variable. Cubic spline type can be used to specify the cubic spline curve fit. Nodal Values can be used to specify the value for each nodes.
Reference frame can be pointed for the variables X velocity, Y velocity and Z velocity.
Mesh motion can be pointed for the variables Mesh X Displacement, Mesh Y Displacement, and Mesh Z Displacement. This option is enabled if the moving body option is specified in the Solution panel.
Element Boundary Condition
Element boundary condition specifies a solution variable on a set of surfaces (element faces). The solution variables currently supported are Mass Flux, Pressure, Stagnation Pressure, Tangential Traction, Heat Flux, and Convective Heat Flux.
Four different types of input are supported namely Zero, Constant, Piecewise Linear, and Cubic spline. Type of Zero is selected if the solution variable must be set to zero. Constant type can be used to provide a constant value. Piecewise Linear type can be used to provide a varying solution variable as a function of another variable. Cubic spline type can be used to specify the cubic spline curve fit.
Surface Integrated Condition
Surface Integrated Condition is used to specify the surface integral of a solution variable. The solution variables supported are Mass Flux, and Temperature. Type of constant is supported.
