In order to verify our simulation, we need to compare our results to either an analytical solution or an experiment. Below is a table comparing the values from the simulation with the calculations from the pre-analysis.

 

Mach Number

Static Pressure (atm)

Shock Angle (degrees)

Theory Value

As we can see from the table, we are getting fairly good matching between the computation and analytical approaches. From this we can build our trust in our simulation.

Alternately, you can select File > Archive and save the project as one file called wegewedge.wbpz. When prompted, select the option to save Result/Solution also. You will then need to save only this file. This is also convenient to e-mail the project. Double-clicking on the wedge.wbpz file will resume the project.
