Molecular Flow Module

Backward Compatibility with Version 5.0 and Earlier

Due to the fact that multiple species are now supported, some variable names have changed. In general, variables will now have _G appended to their names, where G is the name specified for the Incident molecular fluxes in the Dependent Variables section. So, if a model is updated and resolved, the expressions used in results should be changed as follows:

•	The number density should be changed from fmf.N to fmf.N_G .

•	The pressure should be changed from p to fmf.p_G.

•	The reconstructed number density should be changed from fmf.N to fmf.ndr1.Nr_G, where ndr1 is the tag of the Number Density Reconstruction feature.

•	Any other variables can be updated using the Replace Expression button available during results processing.

In addition, new variables exist for the total pressure, number density, and so on:

•	The total number density, fmf.ntot.

•	The total pressure, fmf.ptot.

•	The total incident molecular flow, fmf.Gtot.
