Dear All,

For some kind of purpose, I would like to try if we can use differnt time schemes for the different time derivative terms. but I found it does not work. I add the following information like:

ddtSchemes
{
    default         backward;
    ddt(rho, U)     Euler;
}

I got the following error information:

--> FOAM FATAL IO ERROR:
"ill defined primitiveEntry starting at keyword 'ddt(rho,' on line 21 and ending at line 72"

Anyone knows how to use different time schemes for different time derivative terms? Thank you very much.

change default to none, then you should specify each term individual , and solver shows you which term should be specified
