Default Problem compiling solver using lookupOrDefault()

Hello everyone,

I am currently trying to modify the reactingFoam solver. I am adding the function to define Schmidt numbers for each species using a subdict in the combustionProperties file.

In the first stage this was done using a simple lookup() command and worked perfectly. Now I want to add a functionality, that sets the Schmidt number to 1 for all species, where there is no entry in the dict. For that I intend to use lookupOrDefault(). This is the line of code I am using for that particular operation:

scalar Sck = readScalar(SchmidtNrDict.lookupOrDefault(Y[i].name(), 1.0));
When trying to compile this, I get the following error message:

no matching function for call to 'readScalar(double)'
As far as I understand there is a mismatch between the input type of readScalar() and the output of lookupOrDefault(), but I can't figure out exactly what it is.

It would be great if someone could help me find the mistake! Thanks!

Ok, I solved the problem. In case anyone ever runs into this problem again (or perhaps I am just extremely bad at programming ) the lookupOrDefault() function automatically returns the value of the entry you are searching for. This means that readScalar() was unnecessary.

Correct code is:

scalar Sck = SchmidtNrDict.lookupOrDefault<scalar>(Y[i].name(), 1.0);
