In D3Q27_PF_VELOCITY model activating the option

[AMITG80]

In D3Q27_PF_VELOCITY model , i want to activate #ifdef OPTIONS_geometric. then what to do to activate this model .how to enable it?

[llaniewski]

Options in models create another variant of the model. If you compile d3q27_pf_velocity_geometric it will have the geometric option activated. You can list all avaliable variants of the model with make d3q27_pf_velocity/list

[AMITG80]

if i want to use multiple option at a time then d3q27_pf_velocity_list1_list2 , i have to use for compilation?

[llaniewski]

Yes. The list will give you what combinations of options are avaliable and in what order you should write them.

[AMITG80]

OPT="(q27 + OutFlow + BGK + thermoplanarBenchmark)autosymgeometricstaircaseimpisogradtprec" in this if i want to use thermo*planarBenchmark , geometric and isograd option then how to implement it.please suggest

[llaniewski]

In the "OPT" specification, the + means you can do "one of" options, and * means "any combination of". So basically you can do d3q9_pf_velocity_geometric_isograd

Thank you so much sir

As i am using D3Q27_PF_VELOCITY, in that i am simulating the droplet impact on inclined surface so i want to calculate the surface tension force ,gravitation force as droplet slides so for getting that value in paraview should i use add global function in dynamics.R?

[AMITG80]

As i have checked that there is one global KINETIC ENERGY in the dynamics.R file but i am not able to see it in paraview.

@AMITG80 Please for another question as this is not related to the options mechanics.
Globals in TCLB are global integrals over the domain. They are exported into a .csv as values-over-time, with the <Log .../> element.

Thank you sir
