How to program particle position in Fluent
 

Hello I am new here and pretty new in ANSYS Fluent. In one of my work i need to position a large number of particles in a space. I have the coordinates and radius and temperature of the particle from DEM analysis but its too huge a number of particles to input these datas manually. Is there a method of insterting the tabulated results i have for ansys to automatically input them given teh coordinate and the size?
Thanks in advance for advise.

If I understand you correctly, you want to import points into your model.

You can import points from a coordinate file in the Design Modeler.
Create--> Point--> From coordinate file.
But I am not aware of any method to import temperatures.

Thank you very much for the promp reply. I will try to do what i can with this and ask any further questions if necessary

Hi,
I'm not a user of Design modeler, but I think you described a way to import geometry points from an external file.
If you want to use discrete particle model, you can enable the dpm model, create an injection, and set up the injection type as "file": then, you can choose the file which has to be properly formatted.

I think that if you need only to "load" particles (and not inject them continuously) into your domain you can play with end time of injection and mass-flow in the file, such that mass-flow*end time (I would take the time step size, so to load all the particles in the first time step)=mass of a particle.
