find min/max deltaT
I'm trying to implement the CoEuler (local timestepping) scheme in my solver but I don't think its working. As a simple check to confirm, I want to print the min/max timestep to stdout. I've included the following in main source file of my solver:
Code:
dimensionedScalar maxDt = 0.0;
dimensionedScalar minDt = 0.0;
maxDt = max(runTime.deltaT()).value();
minDt = min(runTime.deltaT()).value();
Info<< "Max and min time steps = "
<< maxDt << " " << minDt << endl;
When I recompile it with wmake, I get an error beginning with the following:
Code:
mySolverFoam.C: In function ‘int main(int, char**)’:
mySolverFoam.C:229: error: no matching function for call to ‘max(Foam::dimensionedScalar)’
So I understand the Foam min and max functions don't accept dimensionScalar types. The rest of the compilation error messages says the min and max functions take basic data types as input, i.e. chars, ints, floats.
I guess, the general questions is how do I find min/max timestep? Also, am I right in assuming the timestep is stored as a scalar field array, i.e. a deltaT for each cell?
I'm a noob at C++ so I think this a simple question for someone in the know. |
