hi there,
I'm implementing a source term in my model and I'm stuck,here it is:
volScalarField rpyro = kncell*wncell*rho*exp(Encell/(R*Ts));
and here what it says when I run it:
"Argument of transcendental function not dimensionless"
I don't know but it clearly says in the guide that to implement exponantial function we need to type exp(term),I defined the dimension for each term but I don't know what' wrong with it.
I've checked out the trans() function and I know it but the point is that I didn't even use it.
Can somebody out there tell me how to work this out please?
Thanks in advance.
