Hi, i wanted to know how to limit a variable between the limits...

I know that my solution for the differential equation, which i am going to solve is piece wise continuous... or rather i am interested in the variable within the specifed limit....

Lets take for example... Temperature -> is my variable to be limited.... I am interested in solution within some temperature range, say from 300K to 2000K... So what i wanted to do is this.. If my differential equation predicts a temperature above 2000K, i want to limit that to 2000K and if the temperature goes below 300K, i want to limit that to 300K...

So, lets say that, i have incorporated this temperature variable in my differential equation and solved. Moreover I write this variable for each time step.... But before this variable is being used, i want to limit tha values of this variable...

Someone please give me C++ snippet, which openfoam can understand

Hi Arun

try
Temperature.max(dimensionedScalar("t",Temperature. dimensions(),300));

Temperature.min(dimensionedScalar("t",Temperature. dimensions(),2000));
