RSTM laplacian volSymmTensorField
 
Hi everybody,

I try to implement a RSTM in OpenFOAM.

I have problems to implement correctly a laplacian-term of a volSymmTensorField:

my Reynolds stresses R_ are defined as volSymmTensorField

and I need the term:
d/dx_n (constants*R_nm dR_ij/dx_m)

I have implemented it in OF by:
volSymmTensorField laplacianR = fvc::laplacian(constants*R_,R_);

The code can be compiled without any errors,
but the simulation stops always at this position with errors...

I have seen that the RSTM: LaunderGibsonRSTM includes the line
//- fvm::laplacian(Cs*(k_/epsilon_)*R_, R_)
but it is commanded out,
Blending it in results in the same errors:

Has anybody an idea? Do I maybe need a special laplacianSchemes?

Thanks, Thomas
