Flow3d / Fortran
 

Hello dears,
I think there is lack of information on customizing flow3d using fortran. I see some guys from Flow3d company, can you please help us with proving more tutorial on this case?

tnx
p.s: guys please share any experience u have in this case we may get to a solution sooner.

The most comprehensive source of information on customization is the user manual chapter on customization (Ch. 9 as I recall). It includes descriptions of the important requirements, procedures, variables, and routines, as well as some example customizations. There are a few other example customizations in the comments of the customizable FORTRAN routines, too.

Customizing flow3d must use fortran 9.1? A higer version can do? thanks.

You can probably get a newer compiler to work but there is a specific version recommended in the user manual because it is tested with that version of FLOW-3D and known to provide good results.

Intel FORTRAN 11.1.048 is recommended for customizing the latest version (v10.1).

Dear dmilano,
I want to simulate the welding process, to creat the droplet, how can I modify the source terms of mass conservation equations to add the mass of droplet? BTW,except for this way,are there any ways to creat the droplet? Thank you.

You can use the "droplet source" model to generate spherical fluid droplets without having to customize the code. The inputs are not available in the GUI, but they can be defined by editing the prepin file manually (using ctrl+e in the GUI or in an external text editor). The variable descriptions and some instructions on using the model are available in the Input Variable Summary and Model Reference chapters of the user manual

"droplet source" model ?You mean that I just edit the prepin of FL(Fluid droplet / Bubble source)?

Yes - the relevant variables (NDROP and XDROP, for example) are just added to the $FL namelist of the prepin file.

I got it.Now I want to simulate the process that droplets impinge onto the substrate of steel, I must consider the surface heat source of the substrate, how can I realize it?Thanks.
