Re: Changes to parstokes Solver?
Hi The patch below fixes the case. There seems to have been a misunderstaning of the role of the variable initialization statement in Fortran, which is very different from c/c++. Fortran initializes the variable only once (not at each re-entry) and so the initialization also implies saving of the va...

Re: SuperLU
Hi,
made the changes as you suggested (in the SVN). Can't test it atm though, maybe you
could give it a try?

Re: Integral COnstraint for single Solver
Hi, there is also a second system if you have constraints such that you can attach the new rows to DOFs of the original matrix, namely A % ConstraintMatrix. An example of using this to constraint values on a boundary to given function would be: p => Solver % Variable % Perm CM => AllocateMatrix() CM...

Re: Integral COnstraint for single Solver
Hi, The AddMatrix system adds new global row(s) to the matrix that are shared by all partitions. You can think of them having globally indices from 1 to max_partitions(addmatrix%numberofrows-a%numberofrows). So, no, the partition AddMatrices are not independent, but share the row numering. If you ne...

Re: Output Length Exceeded Error
Hi,
unfortunately the gfortran compiler packaged with elmer windows
binaries doesn't support allocatable characters at all, so the current
svn sources are unusable with current windows binary installation.
I'll try to update the gcc in our packages, but that'll take some
time....

Re: Output Length Exceeded Error
Hi, i changed the sources in SVN such that allocatable character strings are now used instead of fixed length character strings. This particular problem shoud not occur after fetching the sources and recompiling, regardless of the MAX_STRING_LEN setting. The allocatable characters are somewhat newis...

Re: dBasisdx over Edges
Hi,
the derivatives from ElementInfo are with respect to global coordinates.
In your example the edge might be oriented along y-coordinate, for
example? If you need tangential derivatives, take a dot product with
edge direction vector?

Re: parallel AVWhitney: DefaultDirichletBCs IterSolve Failed
Hi Eelis,
impossible to say anything w/o having the whole model. Have you
tried with "Linear System Preconditioning=None"?

Re: Convergence of Whitney-AV Solver
Hi,
If you haven't done so already, you could try using BiCGStabL instead of TFQMR, also
adding "BiCGStabL Polynomial Degree=4" might help(?) GMRES with the
"Linear System Gmres Restart=n" is also an option.
Using ILU might actually make things worse.
