This chapter contains an overview of the work with CHAMPS-BES. Here is a screenshot of a typical layout in the CHAMPS-BES User Interface.

Typical layout of the CHAMPS-BES User Interface.

Modeling a building envelope or construction detail with CHAMPS-BES is quite simple. Here's a summary of what the user needs to define for a complete project/simulation:

•	Geometry/Construction

•

Materials

•	Initial conditions

•	Boundary conditions

•

Outputs

•	Modeling options

•	Solver settings

New CHAMPS-BES projects can be generated either by using pre-defined templates or by setting up a simulation from scratch.

The recommended order of setting up a simulation is given below (the user can use this as a check list):

1.	setup construction (Construction/Discretization view)

2.	import materials (Materials view and Material Import Dialog)

3.	assign materials to construction

4.	discretize grid

5.	specify initial conditions (Conditions view and Initial Condition Edit Dialog)

6.	specify climate conditions and boundary conditions (Climate Condition Edit Dialog and Boundary Condition Edit Dialog)

7.	assign conditions to construction

8.	define output grids and formats (Output Grid Edit Dialog and Output Format Edit Dialog)

9.	define output files (Outputs view and Output File Edit Dialog)

10.	assign output files to the construction (hereby specifying where outputs are needed)

11.	set modeling options (Modeling/Simulation Setup Dialog)

12.	set solver options if the user wants to tweak the default settings (Solver Setup Dialog)

13.	and finally run the simulation (Simulation Run Dialog)

14.	after simulation is completed, start post-processing

At any point during the modeling process, if the user should by mistake do something the user didn't want to, just use the Undo/Redo feature to correct it.

Alternatively to the built-in output conversion feature, the user can also use the Output File Converter to convert the simulation output to input files for various post processing tools.
