Re: Sliding and non penetration
Hi, I'm coming back to my problem. I don't understand exactly how Dirichlet conditions are applied with the Normal-Tangential system, but I assume that a normal is computed for every BC nodes and that at each nodes the normal is the sum of the normals to the elements the nodes belong to? It seems fo...
Re: emacs
Thanks for the tip Carlos. As I'm a vi fan I did a quick syntax file for vi. to put under ~/.vim/syntax/sif.vim if version < 600 syn clear elseif exists("b:current_syntax") finish endif syn case ignore syn keyword SifType Real Integer Logical String File Procedure MATC syn match SifNumber ...

Re: Sliding and non penetration
Hi Juha, Yes I tried the "Normal-Tangential Velocity Rotate = Logical False" flag. It has no effect if I use a Slip coeff in direction 1, but I get very high vertical velocities if I use the Dirichlet Condition with this flag. If I reduce the "large number" I see an increase of t...

Re: Sliding and non penetration
Hi Juha, If I put a large number for Slip Coefficient 1 I get zero velocities (in every direction), so that the no flux condition is respected, but I loose my sliding velocities. What about 2nd order elements? Would it be possible to add the definition of 715 elements in the function GetElementSide ...

Sliding and non penetration
Dear all, I'm loosing mass through my bottom boundary where I have a sliding law and a non-penetration condition in Normal tangential for the Stokes Solver: Boundary Condition 2 Target Boundaries = 1 Flow Force BC = Logical True Normal-Tangential Velocity = Logical True Velocity 1 = Real 0.0 Slip Co...

Save Scalars and Parallel Reduce
Hi in the SaveScalars, for Boundary integrals there is lines like this DO j=1,Model % NumberOfBCs IF( BoundaryHits(j) > 0 ) THEN IF( TRIM(Oper) == 'boundary int mean' ) THEN BoundaryFluxes(j) = BoundaryFluxes(j) / BoundaryAreas(j) END IF WRITE (Name,'(A,A,A,A,I2)') TRIM(Oper),': ',TRIM(VariableName)...

MUMPS workspace too small
Dear Elmer Developpers; I've had troubles recently with mumps for big parallel simulations; The error message from mumps is WORKSPACE TOO SMALL FOR DMUMPS_ ERROR RETURN ** FROM DMUMPS INFO(1)= -9 etc... It's possible to solve this problem by defining mumps control parameter icntl(14) (i.e by adding ...
