If you have several simulation tasks to do or you want to see your CPU glow, the best to do is to create an ENVI-met Batch File (.EBF).
A batch file is a simple text-based list of up to 50 different Main Configuration Files that will be processed sequentially.

You can create an ENVI-met batch file with any text editor or use the standard configuration editor from ENVI-met. Please make sure that your file contains no formatting instructions or other non-text information.

The file structure of the batch file is extremly simple:

00: A remark line
01: MyConfiguration1.cf
02: MyConfiguration2.cf
03: MyConfiguration3.cf
...

The first line is a remark line that will be ignored by ENVI-met.
Then, a list of Main Configuration files follows. ENVI-met can store up to 50 simulation tasks in one batch file- that should be enough even for a longer weekend…

The first step to do is to create the single configuration files and test them individually using the Test Model Function.
Note, that if one of the files in your batch will cause ENVI-met to stop running, the remaining files will not be processed.

Then, create your batch file by writing up all the configuration names in the sequence you want them to be processed. You can add folder/path names, but the usage of alias names is not allowed in the batch file itself.

To start your batch file, go to the Control Panel and press Run/Test Batch:

The dialog lists all configurations in the batch file.
If you are unsure if your files are all available now, you can press the Test Files in Batch button. This will work like the Test command for an individual file, but will process the whole batch file.
If anything is fine, you can click Start Batch and leave the computer alone for some time.
