How is heat source defined in COMSOL?
Heat Source. The Heat Source node adds a source term Q to the right-hand side of the heat equation: Specify Q0 as the heat rate per unit volume, as a linear heat source, or as a heat rate. The default option for the Heat Source node is Solid, which specifies that the heat source Q0 is defined in the material frame.
How do you plot a temperature distribution in COMSOL?
Then you can do as follows:
- Results: Add a 1D Plot Group.
- 1D Plot Group: Add a Point Graph.
- Select the point that you are interested in.
- Enter the expression to plot in the Expression section.
- Click on Plot in the settings window’s toolbar.
What is the meaning of COMSOL?
COMSOL Multiphysics is a cross-platform finite element analysis, solver and multiphysics simulation software. It allows conventional physics-based user interfaces and coupled systems of partial differential equations (PDEs).
How do you plot derived values in Comsol?
Send a report to the moderators Then select the outer boundary. In the one D plot group, select line plot. In the expression write exitavgconc(c) and then t for the x axis. For example: Model couplings->average (you can change the default name to any other name, lets say exitavgconc) Then select the outer boundary.
How do you plot time graphs on Comsol?
By right clicking on the “Results” node, then selecting “1D Plot group”. Then go to the new 1D plot Group by left-clicking it, and select the probe you want to see in the “Settings” window. Then right click the 1D plot group and add a point-Graph and you’ll have your probe plot in a separate graph.
What is CFD software?
Autodesk CFD is a computational fluid dynamics simulation software that engineers and analysts use to intelligently predict how liquids and gases will perform. Autodesk CFD helps to minimize the need for physical prototypes while providing deeper insight into fluid flow design performance.
What language does COMSOL use?
The Java® programming language is used to write COMSOL methods, which means that all Java® syntax and Java® libraries can be used.
Does COMSOL use FEM?
Is there a way to select which method is used? Hi Derek, COMSOL is based on finite elements, nothing else. COMSOL uses finite elements primarily but not exclusively.
How do I change the legend position in Comsol?
In the settings window for the 1D Plot Group that contains the Line Graph, expand the Legend section and select a Position from the list: Upper right (the default), Lower right, Upper left, or Lower left. In the current version, 4.3a, you can also choose Middle right or Middle left.
