Hi Foamer

For interFoam solver, in pEqn.H, line 62

p == p_rgh + rho*gh

why it use == , but not = ??

can anybody explain this?

thanks a lot!

operator== enforces assignment, even if the path field is of eg. fixedValue type, which is not changed by operator=

Hello

I need to print a parameter in unsigned long long format. I face overloading error.

I would appreciate it if you could please let me know how I could solve it inside OpenFOAM.

unsigned long long b;
Info<<"after operations inside code b is "<<b<<nl;
p, li { white-space: pre-wrap; }

Best wishes,
Sina
