I finished running, and exported the necessary values for enthalpy calculation, such as p,T,c_i(molar concentrations). However, I did not export the enthalpy.

And I need it now, can I restart at every output time and use some tools to recalculate it?

two general options:
1- if values are saved in volField format (volScalar or volVectorField) and can be read by paraview, then use calculator format

2- write some pieces of code to read those values and returns enthalpy, for example look at source code for wallHeatFlux
