Issue711 heat convection coeff if else
Created by: katharinabr
As part of the refactoring in #711 (closed) , I have renamed the convention heat transfer coefficient considering the naming convention. That means from now on hCon is used. The parameter for setting the calculation method for the heat transfer coefficient is now called calcMethod. Thus the conversion script v0.7.6 to 0.7.7 is updated. After consulting the LTX support, the conversion scripts were cleaned up. I deleted superfluous conversion commands.
