There are a few different ways to launch a HX solver run:
| • | From the HX User Profile | 
| • | RADIOSS Solver Command from Windows Start Menu | 
| • | Directly from Command Prompt | 
 
When directly launching the job from command prompt, 
| • | Start the run the folder that contains the data deck | 
| • | HX data deck  includes at least two files:  *.hx and * .grf. HX jobs should be always started using the *.hx file. This is critical and if this is not followed, the solver run will crash.  This is because the *.hx file has all the key run control parameters. These parameters has to be loaded before loading the GRF file and they are necessary for a successful run. |
