How do I get funkySetFields to play nice with my custom boundary condition? I.e. when I run it I get the following:

Code:

--> FOAM FATAL IO ERROR: 

Unknown patchField type myCustomBoundaryCondition for patch type patch



Valid patchField types are :



52

Respectfully, Gospodin Sideroff

Ps. - I'm not Russian but unfortunately the "Canadian" language doesn't have it's own honorific ;-P

Comrade Sideroff! When the revolution comes the party will forbid custom boundary conditions. I let you off with a warning but please try to get over these bourgeois habits! ;)

Seriously: the boundary condition is "in" your solver, not in a separate library? If it is in a library just add that to libs in controlDict and you're fine. If it isn't then in theory there isn't much you can do. In practice there is a nice workaround: the generic boundary condition: In the controlDict add

Code:

libs (

    "libgenericPatchFields.so"

);

in the "global" controlDict (the one in $WM_PROJECT_DIR/etc) make sure that there is

Code:

disallowGenericFvPatchField 0;

(usually I'd recommend 1). Then OF accepts boundary conditions that it doesn't understand
