Dear OpenFOAM community,

I am playing with the icoDyMFoam solver. I looked at the tutorial and I am now trying to build a simple 2D case: a box with a lid on the top moving up and down.
When running it, I have the following error message:

Could someone give me some guidance on how to interpret this message?

thanks very much in advance

The text after FOAM FATAL ERROR is a situation specific error message (in your case: the method exists, but is not properly implemented)

The stuff with #<nr> is a stack-trace ( (If you're using a Debug-version of OF it might even show you the files and line numbers)

After that follows the source-file and the line number that caused the error.
Note: I don't use "Friend"-feature on this forum out of principle. Ah. And by the way: I'm not on Facebook either. So don't be offended if I don't accept your invitation/friend request

Do you recall what you changed when you got this error, I just got an identical one and am having trouble fixing it.

i am compiling a solver(modified icoFoam)to solve this equation:

dimensionedScalar k=q*l/(U0*mu);
solve (
(Ux = -(k*fvc::grad(psi)))
//(like a boundary condition)
and keep getting this error:

any help will be appreciated.

Assume psi is a scalar, then grad(psi) is a vector which cannot be equal to a scalar, which I assumme Ux is.

Further I believe you need '==' and not just '=' when setting up equations. Further no 'fvm::' command is used, thus no variable to solve for is specified.

I you want qualified help, you need to post definition of the different variables etc, otherwise you will receive guesses just as this on.

hi Niels
good to hear from you again.
i am trying to impose a boundary condition(the Helmholtz-smoluchowski equation) on the walls of my case after the calculation for an electrical field has elapsed.this is to see the effect the field will have on the velocity at the cells next(immediately)to the boundary.
what will be the best way to go about this?any suggestions are welcome
