I am new to both FLUENT and this discussion forum. So please kindly excuse me for being a sophomore.

I have been trying to use DPM to study the flow of a single bubble through a geometry and to further extend it to study bubble dynamics.

I have chosen particle type as 'Massless'.

After running the simulations, the particle diameter was shown as 1 micrometer by default.

Is there an option to change the default size of the particle of 'massless' type?

A massless particle is essentially just following a streamline of the flow, there is no force exerted on it. what do you want to achieve by making it bigger?

Well.. that was a no brainer from my side. I dint know that no force acts on 'massless' particle type. I figured it out, after posting this question, from the FLUENT User Guide.

Thanks for your reply. I really appreciate it!
