Using RSF

Client wanted to know how to use RSF

Client only has license for
Here are the steps to using the RSF:

1. Create your case file

The case file should contain the following:

* Definition of models (transient/steady, laminar/turbulent)
* Assignment of boundary and operating conditions
* Set up of initial conditions. To do this, use Solve->Initialize. Choose settings, and hit "Apply".
* Define Autosave frequency (usually you only need to autosave data files). Note: Make sure that your autosave path starts with ".", so that the data file is saved in a path relative to the working directory. By default, the full path is used, and this is invalid on the RSF and will result in an error.
* [Define any "Execute Commands," options that are executed periodically based on time step or iteration. Note that if you have macros, then you will need to have these saved in a separate file, as macro definitions are not saved in the case file.]

2. Macros (optional)
* If you have macros (in your execute commands) defined, they can be saved using the following "text user command":

file write-macros macro_filename

3. Create Journal file
This file contains the text commands used to read the case, read macros, and then perform iterations/time steps. I've attached a sample case file and journal file to demonstrate what the journal file looks like. It is very short and easy to understand (since I put comments in it!) Also, since the autosave frequency is specified in the case file, there is no need in the journal to tell FLUENT to save. All you have to do is specify number of time steps (in a transient solution), and number of iterations in a steady-state problem.

Note. If you have macros, then in your journal file you must have a line to read the macro file. The command is as follows:

file read-macros macro_filename

4. Log into RSF at <a target=_blank href=""></a>
Enter username and password

5. Create project.
Create your project by clicking on project link, clicking "New," and filling out the form, and then clicking "Add."

6. Add files to project
In the project you've just created, click the "Next Step" link.
Click "Browse" to choose files on your machine to upload
Click "Press start to upload." The files will then upload to the RSF. You will have to upload your case, journal, and macro files.
When you are done, click "Next Step"

7. Pick solver if multiple solvers are available.
Fluent 6.0.20 will be your choice here.

8. Fill out the solver runscript form.
For the journal file, this file must be the same name as the one you uploaded.
You'll have to pick

* gui mode (use NONE)
* the correct solver version (2d/2ddp/3d/3ddp). I'd suggest 2ddp or 3ddp.
* number of CPUs (for parallel FLUENT)

Click "Save Options" to see the official command line that will run.
Click "Save and Run" to go to the next step.

9. Run the job
Click "Run Job."
You can then monitor the results during the computations by clicking on "Refresh".

10. Download solution
Click on the files link.
Select all your files using "Select All"
Zip them into one file by clicking "Compress." A new file will be created.
Download that file by selecting it in the list and then clicking the download icon next to the file.
Once you get the file, you unzip the archive.

11. Postprocess
Use "fluent -post" to analyze each data file

Also, within the RSF, you can delete the projects to reduce disk usage. To do so, you must first delete all files in a project. This is fairly easy to do without explanation.
