Using the value of a variable defined in NED file in omnetpp.ini file

I want to use "numHosts" variable value in the second command [output-scalar-file] in omnetpp.ini by referring the "numHosts" variable defined in NED file.

*.numHosts = 4
output-scalar-file = ${resultdir}/${configname}-h${par("numHosts").strValue}.sca

But this error is generated in simulation running phase:

Scenario generator: Missing '=' after '${varname' at output-scalar-file=${resultdir}/${configname}-h${par("numHosts").strValue}.sca

How to solve it?

One cannot use NED parameters in an ini file. However, iteration variables may be used. Therefore in order to achieve your goal you can create and use a "temporary" iteration variable:

*.numHosts = ${nh=4}
output-scalar-file = ${resultdir}/${configname}-${iterationvarsf}.sca

It generates the following file:

General-nh=4-.sca
