Dear OF Users

I would like to create a mass point source at the wall in OF (Just like the CFX has). I do not want to create a hole for inlet on the wall, so i want to create a mass source for steady input of fluid. Is it possible to do so? Similarly, Is it possible to to inject a 'pulse of tracer' at a certain point inside the body. What would the steps be like and what commands would i need? Say commands for identifying the cell, and adding mass source over there either continuous or as a function of time for pulse. How would it finds its way into the equations?

Thanks you very much,
Mandar

Have you considered groovyBC? i.e. change the gradient of your tracer based on the resolved tracer diffusivity (alphaEff) to maintain a constant tracer flux.
