Using step function in kinetic reaction simulation
Posted 25 Jan 2013 09:26 GMT-05:00 Microfluidics Version 4.2a 5 Replies
I am trying to simulate the kinetic reaction of biomolecule interaction in fludic channel expecting to have association and dissociation phase (concentration of complex versus time) in the same curve. I knew that it is possible to use step function or smoothed Heaviside step function from COMSOL in order to change the concentration of analyte species at the inlet from C=x mol/m3 to C=0 mol/m3 at a certain time. I have no idea how to find this function and what kind of variables I need to defind. Anyone has any experience on this?
